Want more? Try your hand at the buried treasure riddle: • Can you solve the buri...
Your favorite band is great at playing music...but not so great at being organized. They keep misplacing their instruments on tour, and it’s driving their manager mad. Can you solve the brain-numbing riddle their manager assigns them and make sure the band stays on their label? Yossi Elran shows how.
Lesson by Yossi Elran, animation by Artrake Studio.
Going to the box with the instrument found: 35% success rate.
All going through and smacking the manager with a trombone: 100% success rate.

@ThePotato what, mine?
what if the manager responds "ozo"?
My solution:
Pick up each box. If they're about as heavy as your instrument, open it
That's actually not bad, and doesnt break the rules
KittyKiana that is the right answer than the one in video
Sounds good to me.
Connor Anderson if YOU listened , u wouldve heard them say that u cant mark the boxes, shout out what u found, or communicate in any way and can look inside the box before they take u back . they cant take u back if u didnt look into it . 😂 so this makes sense
woooooooow XD

Epilogue: After the musicians' grand success they contacted the label and asked for a new non-abusive manager. The old manager got thrown in jail for ten years.
Yes because that guy obviously should be put in jail for literally kidnapping the band members.

There were 3 minutes given to prepare. And the silence was limited only to what they found.
lol, the drummer got sacked anyway for being a stoner.

As a drummer you are right.... We're dumb af
So how is this even supposed to help them with their poor organization problem skills though?
It would show them clearly why it's bad to not leave your instrument whereever, and why instead they should use the correct box. ;-)
Scar them for life. PTSD usually fixes problems, right?
Just pause at 2:19 all boxes are of different sizes
I guess ir is just like saw
Haha is you going to come over and get me
1) order band members to pick boxes in order of how heavy their instruments are.
2) first band member (who has the heaviest instrument) picks up each box without opening them. they open the heaviest 5 boxes.
3) second band member (who has the second heaviest instrument) picks up each box without opening them. they open the heaviest 5 boxes.
so on so forth. should be within the rules and 100% successful.
That's pretty good
If this counts as a correct answer this will be the first riddle from this channel I’ve got correct
No moving boxes, marking boxes or communication,
So long as the boxes are not moved from where they are, this is fine, just lift them enough to gauge the weight

Why was security in on it? If anything they should be trying to stop this psychotic manager
True
Probably blackmail or bribery
@Dark Pink Cow actually it's more similar to burning your paycheck and then questioning why your boss fires you
I'm dying
He paid them probably
Option 1: You lift all the boxes up to check their weight BEFORE you open up any. You end up opening 5 boxes with a weight similar to your instrument. Since you have played your said instrument for a long time, it is easy to tell which boxes are close to your instrument’s weight.
Option 2: You use this same method, and once you find your instrument you switch its box with the box containing the next musician’s instrument. Then, you switch the box containing the next musician’s instrument with the box that is the closest to the entrance of the room. The next musician finds his or her instrument in that box and proceeds to look for the next musician’s instrument using the weighing method. This continues until the last person has their instrument. (Note: If you do not find the next musician’s box while you are searching, the next musician will have to find their instrument and try to find the next musician’s instrument. If you don’t find the next instrument, simply put the empty box that contained your instrument in the spot closest to the entrance of the room. If the next musician weighs this box and finds it to be empty, the won’t waste a turn and will have a better chance of finding both his and the next musician’s instruments.)
Sorry for how long this is...
Not bad.
Dam ur a genius
That is so clever!!
The musicians can’t find empty boxes because they say at 0:50 that they can’t Tuch the instruments which means that they cannot take them out of the box until after. Your strategy sounded good before I remembered the no touching clue… :)
He said they couldn't touch the instruments, so they can't swap them round
I've rewatched this 10 times, and I'm wondering why the band members don't sue their manager for kidnapping.
Now you see, that’s the epilogue
They could, AFTER they solve the puzzle
The manager has green eyes so if he goes to jail he can just get out
I don't get why people keep getting mad when they demonstrate that it's possible to fail. The video never claimed this is 100% certain to work. He said himself that it only has a 35% chance of succeeding, but that chance is still better than picking at random.
It works better because you are eliminating all loops that do not have your instrument.
The only way the band would fail, is if there was a 6 or longer loop, and the manager could easily prevent that by splitting the boxes into two groups before randomizing each group.
Is mayonnaise an instrument
Eeyore The Donkey No. Horseradish is not an instrument either!
Underrated comment
Yes , Yes it is

No Patrick, mayonnaise is not an instrument.
And here I am saying "Okay so he told them not to touch the instruments, so they can just carry the box in with them because that's not technically touching them"
Singsong423 XD
Well,they would probably have to do the concert using boxes and not instruments :/
i thought the same just take a box and shake it if you hear your instrument you open it
+supahReford ;p that would brake any strings and or fragile instruments.....
What I meant is that they could open a box and if it's theirs just take the box into the room with them. That's not technically touching the instruments, and eliminates the choices for the others that go after
My solution:
1, confirm that one person has a phone.
2, confirm you have service
3, text your friend and ask them to sneak over to where you are and text you which instrument is in which box.
backup 3, if the boxes are heavily guarded or your friend can't get there in time, call the police to arrest your manager and hold him for kidnapping.
4, get a new manager that doesn't have a criminal record.
Well if you’ve been Kidnapped and put in a windowless room I don’t think you’ll be able to tell anyone where you are.
@captainnomekop5056 you realize most police stations have a tracker to where the call was, right?
You know SWAT is going to give the manager a scare.
I have another answer... size. They never mentioned if the boxes are in similar size. Drums would have to be in the biggest box.
That's what I thought it would be.
Lymarie Guzmán Pérez it's still an option
they could have made all the boxes big though
make all of the boxes huge
WaffleCat3367 that isn't mentioned in the rules therefore it is irrelevant.

Gentry Dean it’s literally in *EVERY* vid

To bring a little light!
1. Moving the boxes is assumed to be as sort of marking them:
If not many other solutions are better than the proposed one. Imagine this situation. You make a circle, table... (anything with 10 different positions in 2D space (a line can't be used due to being 1D)). Then the group sets previously the position of each instrument on the grid. The first musician opens five random boxes and locates them in the order of the pre-stablished . Then the next one looks the boxes 5 which are distributed so he knows what is inside each of them. If It is one of the 5 that the other musician picked goes directly to it, if not opens the other 5 to find its instrument. 50% chance for the first one, 100% for the others. See that if the second one also moves the boxes he opens. From the 3rd to the 10th they already know its instrument position.
2. In the case, moving is not allowed. Why 35% chance is that great? (Actually is the best one you can get)
If each of them opened the boxes randomly they would have a 50% chance for each musician. That means a global probability of 0,5*0,5*0,5...=0,5^10=0,00097...%

I actually got this one right for once. I do the same thing with CDs I have in the wrong box.
That's a great analogy for what's going on in this riddle. It helps a lot in understanding why this works.
Wait. If the person found their instrument and took it away. Then the next person who goes to that box won't know which box to go to next because that instrument is missing. So technically only the 1st person would get their instrument
Hey! Good point.
*YOU OWNED TED ED...HERE IS YOUR AWARD*
The box gets removed that way..... That is the why the chances of finding yours increases....
Adrija Rambhatla i think they can't get it. They just show that they found it
Udayon Sen oh ok.
Post more riddles! These are really fun to solve and I love the animations!
My guess before looking:
The first person picks up each box without opening it to feel the weight. They then arrange the boxes in order from lightest to heaviest. Then, each person should be able to guess the weight of their individual instrument in 3 guesses at most.
After watching the video my answer is definitely more accurate.
When you're sty that you were not even close.
They couldn't touch the boxes
the question never said that they couldn't touch the box. it said that they couldn't touch the instruments
They couldn't move or mark the boxes. they could touch the instruments that's it

... 1:09 HOW EXACTLY DOES THIS PREVENT THEM FROM MISPLACING THEIR INSTRUMENTS LATER? Also I'm fairly certain you've already done this one - each one opens the picture they use - then follow the patern...
However if they are truely randomly placed then there's a chance that this can't be solved... and thus the manager is just being a jerk...
2:10 35% chance... yah this isn't even coin flip odds they managed to win, this is REALLY low odds ... they got lucky
Stephen West he's just being stupid if they can't go to the uh thing then he doesn't get money
A 0,35 chance is still way better than the original 0,001 chance. Sure it's still ~1/3 but compared to 1/1024 that's a huge increase in winning chance, just by applying a strategy.
Sander
Think about it this way - A: How does this in any way shape or form prevent the musicians from losing their instruments later - this test is literally doing NOTHING in that way B: Imagine you and everyone you love were given a .35% chance to keep YOUR jobs simply because someone was a bit irked at you (Yes good instruments can cost money - but if you weren't making more money than you cost you would have been flat out fired) - again if completely random and not set up in a order in which the strategy succeeds - you're kind of being a jerk
It doesn't, but it does give the manager a 65% chance of being able to replace the current musicians with ones who don't misplace their instruments.
I watch MinutePhysics so I knew the answer.

I thought i could solve all TED-ED riddles but after 15 in a row this one here made me resign I understand the solution and its brilliant, but its really hard to find. Respect to everyone who finds this
just pick up each box and weigh it to see if it matches your instrument, or even shake it. there are no rules about that. higher than 35 percent chance
That is what I said mate
Nice I only thought about shaking the box :)
But you can only do it to 5 boxes tho
yep. and at that rate you may as well just open them.
Well no you can touch all of the boxes but can only open 5 so you can also pick it up and judge by weight in that sense.

I've watched this series for years, but something still confuses me about this puzzle.
The puzzle explains that they open boxes until they find their instrument. And after five boxes, or after they find their instrument, they are escorted to the tour bus, presumably with their instrument if they found it right?
Which means that this solution wouldn't actually work, because certain items within each chain would be removed after each musician. For example, in the example at 2:30, it's possible that before the singer takes her turn opening boxes, the drummer already found his drums in a previous turn. Meaning that after the singer opens the first box and finds nothing inside, she'd be completely in the dark. If anything, using this strategy may lead certain musicians into loops that will never contain their instrument.
The only way this solution works is if the instruments stay in their box, which seems pretty counter-intuitive to the goal of the musicians, even if it's very much intuitive in a puzzle mindset. I kind of wish TED-Ed had made this a more explicit clue, that the instruments stay even after they're found - I feel like it would've made us really think about how this clue would've been useful as a strategy.
They could've left them in the box while the rest of the band members do the puzzle, and whoever managed to find their instrument would get them afterwards.
@@louise4152 True, but they never explicitly stated this.
This is the question that’s been haunting me!!!!!
The manager literally says you can't touch the instruments. The instructions is to find the instruments, not take them out of the box.
Presumably, the staff would pick up the boxes and load them into the tour bus after all the band members get on board.
It literally says at 0:50 you cant touch the instruments until after
I know this one. The horse's name is Friday!
ExtraordinaryMeatBun Bro
ExtraordinaryMeatBun dude i think youre on the wrong video..

Why does everyone say that on these riddle videos?
ExtraordinaryMeatBun wait where did you get that? Like that's the answer to the question you're thinking of but where is the questioning the video
If you're wondering where the 30% number at 4:18 comes from, it turns out to be exactly 1 - ln 2, or about 30.7%.
You can prove this by solving the limit of the expression at 4:11 as a Riemann sum.
My first thought was- all the instruments are in random boxes, sure, but a drum set isnt going to fit in a box that is longer than it is wide, and would be more appropriate to fit a guitar. You'd risk breaking the larger instruments by just cramming them in boxes they don't fit. Plus, what do they do with the empty boxes once a player has found their instrument?
At the beginning it says that the boxes are all "large" so we can assume that are all of the same size of the box that can fit the biggest instrument in it.
You can't pick up any instrument,you leave them in the boxes even if you find yours,it's not a matter of taking it,it's a matter of finding it.
I guess I missed that part. Ah well, I wouldn't have figured out the solution anyway.
either way the band would play that night by the logic that they can look in any amount of boxes proves they could look in all the boxes and get their insterment
Same...
steamdragonfly -_- they can only look in five boxes whether the instrument inside has already been been taken or not

Alternate riddle, same strategy: You're allowed to discuss the strategy with the band (you're not in the band) and go before them and look into all the boxes and swap any 2, and only 2, of the instruments. You can swap 2 instruments in the loop that is more than 5 instruments (if there is one)

How can you put the most Charming Narrator Voice on someone so grumpy.
Then comes the big question: what happens if another musician finds their instrument in your "loop"? Then you'd come across an empty box, meaning you'd have no choice but to randomly guess, meaning that with each person who finds their instrument, the odds drop pretty significantly.
they don't take it out they just find it
Jacob Wheeler they can't remove the instrument, they just look at it, pay attention to the rules he gave

Songs From the Lake's Head I'm a drummer and I figured it out
What I learnt from this video: when considering a permutation of n elements, the probability of existence of a cycle of length exactly k, with k>n/2, is 1/k. It seems obvious now that someone pointed that out for me.
This woul only work if the manager placed them in the boxes with a system. He could have known about this and placed the drum in the microphone box and the microphone box in the drum box, which would result in a loop of two items. He could have made a loop of two items with all the instruments.
It does work, one will have to link to another and the last one will have to link to the first, it's just a logical chain and it will not guarantee success for everyone, hence why he said 'More than a 35% chance', not a 100% chance. They can only choose 5 each therefore meaning the chain could be cut off before reaching their instrument, or they could get lucky and all get their instrument in the chain early.
and ? if there is only loops of 2 items, it works perfectly well. everyone gets their item in 2 searches.
+Thugli No. This is the crux of the strategy: Any loop smaller than a 10-loop benefits you, since you're going for the box with the picture of your instrument on it. In your example, only the drummer and the singer would ever open those two boxes. The worst case is that the instruments happen to be arranged in a 10-loop.
@Triggerfisk "Any loop smaller than a 10-loop benefits you"
Only by the criteria requested here, that ALL band members must find their instruments. If the goal were to make sure at least 5 of them found their instruments then following this method is bad. 65% of the time there will be a loop with at least 6 instruments in it, meaning that 65% of the time 6 people won't find their instrument in the first 5 boxes they open. Would randomly opening boxes give them about a 50% success rate of finding at least five instruments? The best method would be to have everyone open the first five boxes, then you would have a 100% success rate because each of those instruments' owners would have found that instrument, though you would also be guaranteed that five members wouldn't find their instrument.
jgoemat Seems I didn't fully understand it myself. =) So the 35% success rate refers to the probability that there are no 6-loops or longer. I see. I was wondering how they calculated that.
WTF do you do when you're the last 5 musicians and most of the boxes are empty? Where do you check next?
***** oh I see. Thanks.
why would their manager tie them up in a room, that shit is illegal!
and why would they play for the manager after that!
+Mahamud Hussein ikr
And if they keep losing their instruments, why would he make it harder for them.
He's Phil Spector
+Mahamud Hussein I was rather relieved to see that I wasn't the only one thinking that the manager could have been charged with a crime. LOL Also that it was pretty dumb to make it harder for already scatterbrained musicians. One thing you didn't point out that I thought of was that the manager doesn't employ the band but rather the band employs the manager. That means he held his bosses hostage!
3 minutes is just enough for me to watch a ted Ed solutions BC they have the solution to anything now
I've rewached this five times and I still have no idea how this is more reliable than just opening random boxes
Because it increases the chance of them ALL finding their own instruments
If one of them finds their instrument after opening 4 boxes, it is guaranteed that 3 others will, since their instruments are in a loop.
The room is soundproof, so how would the manager know if the musicians spoke to each other or not?
wow... Your right XD
Because if they find their instrument then they go off to prepare. If they don't they get taken into the tour bus.
The musicians are sealed INSIDE the soundproof room. The boxes are OUTSIDE. They can’t communicate with each other.
Yeh, they'll be dragged away before they can say anything XD
He’d probably trust or expect them to come up with a plan
Do they take the instruments or leave them? Because then what would happen if you looked in a box with nothing in it?
"they are not allowed to touch the instruments"
if they FIND it.
then it count,s but they keep it in there for others.

Thank you for making the drummer come up with the solution
First riddle i solved on my own! I am so proud of myself!
This is a poorly conceived riddle as the answer is not the best option. A musician would know how much their instrument weighs so they could pick up every closed box and narrow down the options. They would then be guaranteed to find what they were looking for. It never says they cannot touch the boxes before looking in them.
It also never said on whether the manager weighed down the insides of the boxes with something like rocks. Which in reality he would to avoid the trick you are trying to pull
+Silverizael How the hell would he think to do that?! You just want to put people down, He was totally right on that one!
hahaha both great answers. They really gotta be more specific in their videos.

MY BACK HURTS FROM JUST SEEING THESE BAND MEMBERS
This manager is a madman
For those getting stuck, think about it with a more simple example. Let's say I'm the Microphone, and you're the Guitar, there are only two boxes, and we only get one pick each. If we both pick at random, there is a 25% chance we are both correct (0.5 x 0.5 = 0.25). But, if we each decide to pick the box with the logo of our instrument, there is a 50% chance of that scenario being correct.
The key here is eliminating duplicate picks. If I go first, and pick correctly, then you are guaranteed to pick correctly as long as we decided ahead of time to pick different boxes. So we have eliminated the scenarios where we both picked the same box, which is a guaranteed fail. Basically we've decided ahead of time that we are either 100% correct, or 100% incorrect, and eliminated two scenarios where we are partially correct.
My potential picks:
- Box with Microphone Logo (KEEP)

Ah, so the point is they are all picking unique patterns. This video did a poor job explaining that. Thanks for clearing it up.
Well there’s a 50% chance you’re correct, both of you. Gambler’s fallacy _says_ previous odds effect present odds, but it’s a fallacy. Right??
Isn't this just the 100 dollar bet thing
yeah it is
Minute Physic ?
no, I'm pretty sure it's the 50 dollar bet thing.
i thought to myself there's another one just like this one.
this video is exactly like the Minute Physics video wtf
Amazing that the drummer can tell what instrument each picture is of!
I solved it in another way, with 50% chance of success!
But it depends. Can people inside count for how long was the person outside opening the boxes??? They can use the time that the next person got invited outside as a stop count point. I will tell you how this will work if this is not contradicting with the rules!
Please answer this
Knight Huskey how?
10 guys number themselves from 1 to 10.
n 1 goes out, opens the first box (they can count boxes from the nearest one).
He sees the instrument, opens up 3 more boxes and waits (if its n 8s instrument he waits for 8 minutes accordingly and so on)
then he opens the 5th box and gets kicked out (50% chance of him finding his own instrument in the proccess, even if he opens random boxes after the 1st one)
People inside the prison counted the time n 1 was outside seeing that the next person is allowed to leave they send the corresponding person to open the first box, and repeat the procces with the second box!
Now everyone wins.)
Knight Huskey yes, this would work. And it would have a higher chance, but I believe this would be against the rules. It seems to convey information to the other people and that is illegal.
Knight Huskey Great thinking though
I don't get it - how can this even work if the manager arranged things completely randomly? Wouldn't this only work if there's actually a system in which the manager arranged things like a chain? How does the math even work out in full? It seems like the chance of failure - having someone's instrument be in a 6th box - is identical whether you have a system for getting to the 6th box or not. I mean - what makes this system better than any rigid system?
Plus - how is this a proper riddle if the answer isn't guaranteed... 35% is pathetic.
Forrest Gump That's what I was saying. Since they were all placed randomly there is no fixed pattern or better way to pick so there is no riddle to solve!
well, the riddle was about finding the 35% success rate solution, after all...
still doesnt make sense......who came up with this riddle.........in the 4 box example.......you literally screw 1 of your 2 chances right away by picking the 1st one wrong.......in the 10 box you have a 40% instead of 50% bc ur 1st pick is 100% wrong........who came up with this riddle geez....if it was placed randomly then you still only have 50% no matter what order you follow.
they cld simply not pick the 1st wrong one eliminate that since its 100% wrong now they have 5 out of 9.......
In a four box example, it may be in the box corresponding to your thing. Also it scale per person most effectively. if it is a 1/2 chance of getting your thing in the 2 or less boxes in your 4 box example, for 4 people it would be 4 * (1/2) resulting in a 1/8 chance for all of them to find it in 2 boxes.
Lets say you open the flute box looking for the flute, but its the drum sticks. You now know that the drum sticks are not in the drum stick box either, so you open it and find the trumpet. You then look in the trumpet box and find the sax. You have now opened 3 boxes and so you know that at least 6 instruments are misplaced. Now you open the sax box and you find the tuba. Now you know that 8 items are misplaced. You now have a good chance of finding your instrument in the tuba box because non of the other items are in their box either. Its easier explained on paper. Draw 10 boxes and label them 1-10. Put a random number inside each box. Pretend you are a number looking for your number. If you are a 1, look in the 1 box. If you find a 2, look in the 2 box. If you find a 7, look in the 7 box. You will always find your number in at least 5 attempts this way.
the probability of all succeeding is 1 kilo bytes
a kibi then
The Drummer is a genius. Many other people would not think of that.
I would pick up a box without open it, an because of the weight know if it is my instrument. Every artist would have a good idea of the weight of their instrument because all the practice they have with it. Besides if you are mistaken you get to open 4 more boxes. I would say this would have higher chances than that 35% solution.
At 3:07 I realised that the probability of me finding this answer is
Ok but how does the drum set fit in the microphone box?
CAT1554 I think he just put his snare drum in there.
CAT1554 You get 10 boxes that are each big enough for a drumkit, then you put the microphone in one of them.
Exactly my thoughts. And what do they do if the box is empty
This is me here watching it.3 years later and I have watched it over and over again
[SPOILERS] you start with your own instrument, you go to the instrument that you find in there. Repeat until you find your instrument. The $100 bet is very similar.
Eh, it didn't make sense to me. Isn't randomly guessing as efficient as the loop method?
I'm a drummer and computer science major.. I thought I was going to get this right for sure haha
When he started talking about time complexities, that's a subject in computer science represented by the big O to represent time efficiency for a large amount of values (n). In this case n=10 (for each boxes). Searching through the boxes for each person would take at the worst case O(n), while the best case would be O(1), and average case is O(n/2). Anyways, computer scientists are pessimistic and always look at the worst case and in this case O(n). This time is special because it is commonly associated with sequential loops (as the one represented in this riddle). Maybe I'm getting theoretical, and thinking too hard
hey, if they were to decide that all of them will open fixed 5 boxes won't 5 of them have 100% chance of finding it? If all of them didn't have to find it, it would have been a better way.
@ Apporva Vishnoi: If they decide to all open the same fixed 5 boxed, then that's a 100% chance of losing. Because just as sure as half of them WILL find their instrument, the other half will NOT find theirs. Since they will play only if all of them find their respective instrument, the half who won't find theirs will assure that no concert will take place.
No because this give 35% for the whole team. If one finds it everyone else will find. While 50% is better for each person the chance of two people finding or not finding in a row becomes 25% if it's 3 it becomes 12.25% and so on. Unless ur alone, this works better (unless choice of opening boxes is a very limited, e.g open only one box)
umm, lets say the first person finds his instrument, will it still be 10 boxes, or 9?
O(n) = O(n/2) you nutcase
Step 1: Confirm you have green eyes
Step 2: Ask the manager to leave
Copied comment
can someone explain this comment to me xD
@@lily-ts4tu its a video about the green eyes riddle
okie I’ll go check it out ty 👌
One of the only Ted ed riddles I’ve ever solved, I’m proud.
1:30 Yes I think I can.
They sue the manager/record label for kidnapping and use the money to start their own label?
Am I the only one who didn't answer the riddle but excited to see correct answer?
I don't know if I'm misunderstanding, but why bother creating a riddle that gives you a 35% rate at success? Not even 50, but 35. This just seems dumb to me.
Natasel he is not debating that. He's saying that why bother make a riddle that has such a low chance of making it. This riddle seems just bad to me. My solution was to kick the managers ass then fire him. Then try to sue him.
Luis theboss I'm a girl :D
Natasel Did you make that up, or is it a thing I've somehow missed out on?
Natasel Well, they say it's an adage, coz a truism refers to an obvious truth.
I do get what you're saying, but it feels weird being called a he. I tried to brush it off when I saw your message, but I just had to correct you. It's dumb but it was bothering me XD.
Lol
Rarely understood Ted ed riddles, still watching every one of em....
no seriously. every gamer can solve this problem. we pretty much do it everyday when we go to look for one game but find a different game in the game case.
OH MY GAHD This is pretty much how I find the game. never thought of it that way XD
Not me, 'cause I always put the game in the right case. :v
I hadn't even thought of that!! SO genius. We just moved and everything's a mess and I'm really upset about the way my partner just randomly tosses one game in another game case and now I can finally sort them with the semblance of a system. Thanks!
Why do people still use discs?
DUDE!!! Awesome real-life application to this problem. HAHA! It blew my mind!
Turns out that the manager made a loop of 10 instruments and swaped them so that the instrument that a person currently was searching for was in last box every time.
Seriously I don’t get how this solution works at all
The key for these Ted Ed puzzles is to use the factors themselves into the equation to find the solution. Normal methods won't work, which is why it's so confusing.
Idk if this is right but I think there’s a better way to do this if its not against the rules. If everybody checked one box at a time for 5 rounds instead of checking all 5 boxes at one time. First round check the box with your instrument on the picture. Second round go in sequential order from the box you picked in round 1 and repeat until round 5. By the 5th round your probability goes up because you checked 4 of the 10 boxes while some of the other people already found their instrument. It’s the same as the 5/10 option but with the progression of each round we gain insight on who now has their instrument, thus we know an additional box not to choose the next round.
Example- ----
We start with 10 people but by the start of the 5th round of choosing one box each round, everybody will have eliminated 4 boxes from the 10 initial boxes. Round odds go from
1st round-1/10 boxes
2nd-1/9
3rd-1/8
4th-1/7
5th-1/6
But as we go from round to round we subtract the boxes with the instruments that were found in the previous round.
Let (X) equal the number of instruments found in the boxes by the other bandmates.
Thus by the 5th round given (X) our odds go from 1/6 (16.6%) to 1/6-X (>16.6% with % variance increase each round given X) verses a 3.5/10 odds (35%) or a 1/1024 odds (0.09%).
The % variance comes in when the first bandmate finds their instrument in the boxes. If 2 bandmates finds their instrument in the 2rd round then in the 3rd round everybody will have 1/6 odds instead of 1/8 because everybody checked 2 boxes and 2 were eliminated. And by the start of the 5th round if 4 out of the 10 bandmates found their instruments then you now know not to search those 4 boxes and not to search the 4 boxes you already searched. That leaves you with 2 boxes a 50% chance.
