These were so easy, I thought there must have been some hidden deception I wasn't getting. I spent two seconds coming up with the answers and about two minutes wondering what I was missing.
Year, so did I. Had both answers correct within a second, but due too the huge percentage of people who got it wrong I became unsure if I haven't missed an important detail.
@@Anonym-iv3tz same😂
I got answers within 10secs,the 2nd one got me thinking for 8secs,but I thought that i was wrong lol
Yip, I thought they were gonna be trick questions because they were so easy🤔. 73yrs old here.
same and i am 13
These problems are definitely not designed for 15 years olds. Aren't they way too easy?
They are designed FROM 15yo's
+Will Robinson a seven year old does not have the necessary intelect to be able to have the thought process needed, these questions are more complicated than the basic addition and subtraction or multiplication children do at that age.
no they are GCSE (lower than what I learn in The Netherlands, we have vwo, not vmbo (search it up) i'm 15 years old and got them both right)
***** yea you're not seven though, I said a seven year old could not do them.
I said it to m1croWATCH
Pretty sure there was 0 people on the train. You know, to begin with.
...okay
haha ha
You are wrong sir, you forget that trains need people to drive them
So the guy driving the train was there from the beginning? He just stood there before the train started? :P
+Elliot Sveum
Sorry, when the train was made where were the workers? Did the train complete itself? Also when the train is turned on for the first time you need someone to turn it on. So there is always someone when the train is turned on. Drivers change but there is always one if you want the train to move.
😭 There's no way that these questions are made for 15 year olds. They're too easy. I wish those kinda questions appeared on my exams.
TRu
15 year old dogs maybe. My poodle missed the second one.
I still have the 5th grade US math book from when I was in public school in the 1960s. There are story problems mid way through the book which are more difficult than these questions. At that time, it was possible to start 5th grade at age 9 if one’s birth date were before November 1.
Im 12 and solved these kinds of questions when i was 10
Don't forget that these questions are designed for Americans. They're not too bright.
Adults as in High School Drop-Outs?
More like elementary school/kindergarten dropouts... This stuff is so easy! -_-
Forte Piano that would be about my only concern if we're High School dropouts I get it but actual high school graduates not a chance in hell would they miss easy questions like this
More like not educated
I dropped out in high school, got my GED a year later, and these were overly simple.
even a class 7 student would solve this.... the adults talked about in this video who cannot solve are basically aliens.
The difficulty in the two questions lies in the fact that they are so simple, you spend an unreasonable amount of time in wondering where the 'catch' is.
Offshoreorganbuilder exactly!
Usage. Historically, dice is the plural of die, but in modern standard English dice is both the singular and the plural: throw the dice could mean a reference to either one or more than one dice.
Joseph Inhiding AN ordinary, fair dice marks the singular pretty clearly imo
@@josephinhiding3595 I'm afraid I must disagree. Using 'dice' as the singular would be considered an obvious blunder, in my world(!) though he did say '*an* ordinary dice, so I suppose that clearly implies 'one'.

Wait, THESE are the questions that are designed for 15 year olds there? We did these when we were 8 years old...
Taha Serdar Arlı right? xD
Kids these days are being dumbed down due to their excessive reliance on tech. My parents wouldn't let me use a calculator for basic math. (I was born in 1985 btw)
Andrew DeSalvatore I meant that the questions asked in my country are way harder. I count as a "kid" as well, as I'm 16 years old.
But that other bit interests me, you're telling me people can't even do basic math because their parents let them use calculators. That's concerning, to say the least.
I'll check the US's curriculum for highschoolers to see how bad it is.
Taha Serdar Arlı Some people aren't able to do multi-step math problems in their head quickly. There have been times when someone asks a simple question in-person & people just take a little bit to answer it. Or they just turn to me for the answer (or I overhear the conversation and blurt on the answer).
I also work retail so the biggest problem people face is interpreting $5.99 as $6 instead of $5. I might just be venting, but there were a few customers I've had (full grown adults) that I pretty much had to argue with that you're not multiplying $5 times 2units. I understand where they're coming from 5.99+5,99, your 1st instinct is to say 10.98 but that's wrong. 6+6 = 12. then subtract the 2cents, 11.98.
I'm sure just like anywhere, I'm more likely to remember the shockingly stupid people. No matter what state/country/continent you live on, there will always be stupid people. Heck, I remember a GF I had, that thought she made A LOT more money than me at her job because they paid her everyOTHER week... compared to my EVERY week paycheck. So her paycheck would be double~ of mine... but I just couldn't get thru to her. She was a good girl, but math was not her strong suit.
10 yrs for me
Okay, I don't believe that 25% and 46% people missed it.. These are most easy questions there can be..
It's surprising how many adults don't understand basic maths skills anymore. If you're still at school, ask your parents some of the easy questions in your year group and i bet they will get some wrong
@@nathan194gamer8 why you say his fathers should fail? My mother learned to operate with integer numbers when she was 14 (that was 60 years ago) and that was the last year that she attended school. To this day she can still operate with integers perfectly. I think that people today are even more idiotic that some decades ago, and I think it has to do with so much media in our lives and that people read less and less books everyday.
cuz adults always think these are trick questions and come up with ridiculous answers for them
chinmay kulkarni you have to remember that these percentages are from random people most likely from the street who are in the process of doing something else and are not at their best cognitive self. As we are watching a video actively challenging our mind to see if we can answer the questions. Stats can be misleading taken out of context
Mush Tacular Yes, stats can be misleading but I keeping hearing in the news of all these types of debts, be it college or credit card, people are enduring.
Remember: 42% of adults don't know how to divide by six, 100% of adults have to file their taxes.
lol true
XD
nah they can pay other ppl to do that for them
or they does not know how a fair dice looks like... :P
Remember: 1 person may not be able to write 46% correctly if s/he wants to copy the number from a video.
:D
I solved both in a total of 10 seconds. I'm 63 years old, and it's nice to know that I still haven't become an adult yet!
To be fair, he said that a portion of the adults got the wrong answer so there are still adults that answered it correctly (like you for example)
😂😂

For question 2 I went: "420 divided by 20, simple, 21!" Because I'm so used to rolling d20's
Then you started explaining the answer and I realized while TECHNICALLY I was right because they never specified the amount of sides an ordinary die has, that the question was referring to a d6.
I quickly changed my answer to 70.
...an *ordinary* die... a die with more or less than 6 sides isn't ordinary so TECHNIALLY you were not right because although they didn't specify how many sides, they said an ordinary die which means 6
@@teho1536 No die is ordinary. They are contrived human-made inventions, sometimes carved out of a morbid substance like bone. Even if (and that is questionable) they have become commonplace, doesn't make them "ordinary" (techinqually).
@@timothyLucasJaeger a standard 6-sided die was the first die to be invented... therefore ordinary
@@teho1536 Does that make the first religion to be invented the ordinary one, or the first form of torture to be invented the ordinary one?
@@timothyLucasJaeger Sorry I could have phrased that better. I meant, when someone makes a game which uses dice, they will use a 6-sided die as it is the standard unless that game requires a certain amount of sides. If it doesn't NEED more or less sides, they will use 6.
I can guarantee this is not what 15 year olds are doing, this math at a 5th grade level tops. 15 year olds will be taking trigonometry or calculus
I think geometry or algebra is more accurate for 15 year olds
yeah, 15 year olds be taking algebra, trigonometry and calculus are a few years later
Where do you live where 15 year olds are doing calculus? That is a 12th grade level or college level subject. Basics of trig maybe, but not calc.
+fredhenry101 For most people that would be true. I knew a guy once that was taking calculus as a 15 year old sophomore in high school. I, on the other hand, bloody near flunked algebra as a freshman.

LS95 Ya, same. But they're so easy!
same
Ye hahaha same especially since it took me 1 sec to arrive at both answers lol
I dont get how some people can't get these questions.
indeed
They are adult, thats why lol
Not everybody has been exposed to math the same we presumably you and I have. It's perfectly understandable that some would struggle with "basic" concepts such as probability and arithmetic (seeing as most don't use formal mathematics on a daily basis).
I think exploring why they didn't get them would be more interesting than the simple fast they missed. Was it a multiple choice question? Were they not invested in thinking about the problem? Did they have test anxiety and assume the obvious answer must be wrong?
For the probability question, was it failure to understand the probability? Error in division? Or confusion about the question, seeing as "dice" as a singular is not the more common usage. I can see an adult misreading the question as a pair of dice, not knowing the answer and guessing wrong, for instance.
I think it could only reasonably be attributed to poor wording, or the poll being run on mental patients.
The second problem doesn't give enough information, because it doesn't specify that this is a _6-sided_ die.
very true.
also 70 is not the expected outcome, it is simply the single most probable. To be honest i while would not expect 70, i could reasonably expect 65-75 range. Random does not mean average.
It says an ordinary, fair dice. That's six sided.
@@andrewness A 4-sided die is fair and not uncommon.

These were easy for a 56 year old guy like me. I also know that you do not roll a dice. You roll a die. If you have two or more then they are dice.
and i guess were assuming it is a 6 sided die and not another type
I don't know where you live but at least according to the oxford dictionary the singular is also dice, but with the addition that die and dice are acceptable singuli, but only through language evolution. You are right that die used to be the only singular but times change language and luckily english isn't as strictly controlled or restricted as is french.
The dice one could also be 420 because you could expect to roll 3 all 420 times
+JB Crocuta French language is not restricted at all. there is new words everyday...
+Alexander Breizh thanks...of course. i didnt mean completly restricted. of course french evolves as well. but compared to other languages it takes more time since the change is more or less governmentaly controled through an institution. and english and german for example dont have that. and the oxford dictionary and the duden only give guidelines but dont hold any decisive authority on what is correct or acceptable.
FWIW, question 2 should say "a fair die"; "dice" is plural.
you can go dice
Sadly because of so much misuse both die and dice are accepted as singular...
'Dice' can be singular.

hamfister That I did not know! Thank you for the correction.
I think if they used die probably a further 50% of people wouldn't understand the question lol
420 is a pretty high number of dice to be rolling ;)

It said "An ordinary, fair dice is rolled 420 times". This means one die, which means that this statement doesn't work.

how was this missed by anyone?
Ikr
ikr too
the first question became viral after there was an error on a correction sheet I believe, the answer was logical but the correction sheet said 46, which lead teachers to justifying giving 46 as the correct answer.
Don't know how the 2nd question was missed.I got it right. The 1st question I missed because I used the wrong formula. I used 63 - 19 + 17 when it should have been 63 - 17 + 19. Not sure why as I would think you would add 17 (17 got on, not off), but it works.
The right way uses the inverse. Imagine it like a staircase: if you originally go down the steps, to reverse it you have to go back up the steps the same was that you came, there is no other way.
In question 2, "an ordinary, fair dice" might be unclear to US audiences as a single unit is called a "die", so the question should read either "an ordinary, fair die" or "a pair of ordinary, fair dice", both of which would result in different answers. "Dice" as a sigular noun is, however, common in the UK, and these questions were asked of UK adults, so it makes sense.
It literally says “an” which means it’s singular no matter what
The grammar threw me off too, so I came up with two answers: 70 if it's "die" and 140 if it's "dice".
In what country is this a question for 15-year-olds?!
The adults are in the UK
It's UK Year 2 SATs, which is actually for 7 year old kids and not 15 year olds as mentioned in the video description/later sources (original source: twitter.com/LouiseBloxham/status/729027334284709893/photo/1, which was first brought to mass attention via metro.co.uk/2016/05/08/people-are-getting-confused-over-this-simple-maths-problem-for-no-good-reason-5868518/).
Should be for 8 year olds....

I don't really see how adults couldn't get this? Did they drop out of high school? Not trying to be mean but I feel like these are things people shouldn't forget.
I asked adults at my work place to solve a simple equation. They did not know order of operations.
Golden Duck Jeez that's rough :/
***** I agree. I sometimes can't believe it.
Easy to miss it: ask random people on the street while they have their thoughts on totally different things. Some people will answer without thinking, some may be stressed ...

To me, an "ordinary" die is a d20, so the answer would be 21.

I find it very fitting that this comment has 69 likes rn
I am curious what errors these 25% and 46% of adults committed when attempting to solve these problems. Would you elaborate on this, please?
In the first one, the 25% were probably smart-asses and said that there were no people on it to begin with, or just one (the driver). I don't understand how that the 46% of adults missed the second question though, as it is a process of short division, which in most cases can be done in your head.
Maybe the people weren't aware of the possibilities in this situation (that every number is meant to appear with a possibility of 1/6)
I think people calculate the first one the wrong way: they substract the 19 who werent on the original train and add the 17 New passengers. I guess?
I meant people do this in their head:
63-19+17=61
Only way you can get a wrong answer, or something.
For the second, it could be that the adults, rather than using 1/6, they may have mistakened it for 3/6
Nobody should be proud that they got these right. If he is right about the percentages of people that got those wrong, that's very scary. I like how he didn't even use a variable to solve first problem because he probably knew it would confuse people who got it wrong.
I used x-19+17=63 and worked it out
I can't speak about the second problem, but the first problem was a dumb "viral" math problem where the supposed correct answer from the answer book was 46. The question was a poorly worded trick question which apparently was asking about the number of people who were on the train to begin with after the 17 new people get on the train. Which is 65 - 19 = 46 people left on the train who were there to begin with, who did not recently get on. It's a stupid gotcha question that entirely depends on interpretation.
I don't believe he is correct about it being a question for 15 year olds. But I could see that the percentages of adults missing could be right. I don't know how it is these days but I went to school in the 80s and know they used to tell the kids back then not to worry about math because they "will never use it again after school." I heard that on TV. I heard that from other kids' parents. And I even heard teachers telling that to students.
Hopefully, that mentality has changed now. I know in the 90s, they started to preach math and science to girls to try to get them interested in other careers. Teachers in America are not very smart when it comes to math so it is not surprising to hear them down playing it. Even math teachers only know so much. They tend to focus more on teaching skills and education theory than having solid math foundation.
So that being said, I can see 25% of adults missing these questions since that is probably the same percentage that would have gotten it wrong when they were in school. When the kids are told by teachers that math doesn't matter, then the kids will believe them. They start guessing their way through math, getting minimum scores to pass without giving an effort to understand.
I did student teaching for 1 year about 15 years ago. One class I got, the regular teacher let me know that some of the kids will sleep in the back of the class and it was best not to say anything to them. Sure enough, several would come in, take a seat in the back, and have their eyes closed the entire period. I asked some of the other kids in the class about their behavior and they confirmed what the teacher said - that it is what they do and we "just let them do whatever".
ahpacific i just subtracted 17, and added 19. Variable are ok, but for problems this simple, they just make it more comp...Oh. OH.

Took me about 3 seconds for the first one, and the second one I got instantly as I read it. It would be interesting to know why so many adults got them wrong since a 12 year old should be able to do this. I’m in the UK and I understand that different countries have different maths abilities by age because of how seriously they take maths education. I knew a 30 year old guy with a full-time job, and could read and write, but didn’t understand the concept of a percentage. I.e. that 20% of one quantity is different than 20% of a another.
Or that an percent increase to a percent chance isn't just adding the increase value to the original chance, ie, if a thing occured 10% of the time before the increase, and there was a 25% increase, it doesn't now occur 35% of the time, it now occurs 12.5% of the time, because 25% of 10% is 2.5%.
@@GirishManjunathMusic that's why you differetiate between percent and percentage points. An increase of 25 percentage points would equate to 35%.

I would love to know more about the testing. Why people missed seems a lot more important than self satisfied gawking.
English kids are generally taught at a higher level than American ones, in schools.
The reason why so many adults miss these is that they overthink it. The simplicity of a child's mind sometimes can invoke the realization of the most basic and logical solutions.
when you say dice- that implies a pair. I was figuring it out as having to roll a 1 and a 2 to equal 3, which was a 1/36 chance. Your question should have read "die" not dice. IMO

You have a 1/18 chance of rolling a 3 with a pair of dice.
@@danielpittman889 You have a 1/18 chance of rolling A TOTAL of three with a pair of dice. That's relevant to a craps player. For a backgammon or parchisi player, you have a 13/36 chance of rolling a three -- 31,13, 32, 23, 33, 34, 43, 35, 53, 36, 63, 21 and 12. ;-)
Right. Although saying "a dice" colloquially means a "a die", and a "a pair of dice" unambiguously means two units of die. The word problem needs to be unambiguous to be fairly interpreted.
NOBODY talks about one 'die'. The idea that 'die' is the singular of 'dice' exists only in the minds of English teachers and pedants generally.

Exactly. It also assumes that the die is six sided. That is the most common, but some game players will point out polyhedral dice.

@@BrainPermaDeD I first used them in Dungeons and Dragons, and they are used in a lot of other Role Playing games. Its useful to have random number generators for 1-4, 1-8, 1-10, 1-12, 1-20 and 1-100 rather than the plain 1-6 :)
Dice is used for singular and plural
You never specified what kind of dice it was - d20, d10, d3, d100? :p
what is with the picture of a letter for your youtube account? I see them everywhere anymore.
It does specify it actually, it says “an ORDINARY, fair dice”, which obviously implies the standard 6-sided kind.
It replaces the old default avatar if you don't have an avatar.
+Badly Drawn Turtle In dnd we use d20s most commonly, so to us that is the ordinary die. The question is stupid, because it assumes that people don't have different standards than the author.

I think these problems are too easy even for 15-year-olds. I can see 5th graders finding the correct answers to these problems. I wanna know how the adults couldn't solve the problems. I'm 31 years old and they were a piece of cake.
wow, you solved a 10th grade math problem at 31? where's your medal?!
I never said that I did anything special. All I'm saying is that I'm smarter than the roughly 40% of adults that got the problems wrong.
+Nathan Warford that would make you average i guess.
JK. I also don't get how People get this wrong.
In germany we learn about probability in 9th or 10th grade, so only very few 5th graders would be capable of answering the 2nd question over here. Dunno in what grade it's teached in the UK though.
And btw.: When I joined an university that offered only maths heavy courses (engineering and IT) the first week was a revision on fractions, since that'S what more than half the students always struggle with. That was hilarious.
I don't see why this needs to be taught. The questions are at a level where the answers should be intuitive. I'm confident that as soon as I knew how to do division, I could solve both problems. Which was around when I was 4-5 years old.
The problem I’ve always had with math word problems is that they’re always written with an awkward syntax. They’re usually harder to understand because no one would actually say something in the way they’re written.
"An ordinary fair dice" is missing 'Standard'. Better terms would be: six-sided die, one six-sided dice, or a picture of one

I would have liked to see what answer they came up with that was wrong just so we can see what the failure point is, because these both seem really straightforward and like others I spent more time wondering if I missed something than figuring out the answer.
For 15 year olds? Could you not give these questions to young children?
Yes. I teach year 5-6 children (9 to 11) and would expect most of them to be able to answer these questions easily. I find it very hard to believe that they were designed for 15 year olds; however, I can easily believe that a lot of adults would get them wrong; a lot of adults seem to forget everything they learned at school very quickly!

From an adult standpoint, I think it boils down to something as simple as comprehensive thinking. Carpenters are reminded to measure twice and cut once. If we act too quickly, a small detail may be overlooked, thus leading to the wrong conclusion.
For the second question, the word “dice” is plural, the singular is “die”. So based on this, it can be inferred that two dice are being rolled. A natural 3 would occur 2 times for all 36 possible combinations. In this case, a natural 3 would come up 23-24 times in 420 rolls. (23.3 repeating)

The only reason these may be difficult is if you are used to only doing sums, rather than reading wordy questions.
For the first question, I'd actually do x-19+17=63. It makes it clearer what is unknown, and how you're building towards the known final number of passengers.
For the second, I'd be interested in what the wrong answers were. Did they just guess, or perhaps not know their times tables?

The second question requires a specialist knowledge of the definition of "expected value" from statistics. The actual odds of getting exactly 70 rolls of 3 is small. Though it is the single most likely result and the average result for a large sample size, the odds still favor some other result because there are so many other possibilities.
it says in the discription they where from the UK
Regarding the Dice question, there is no information given on how many sides the Bice hat. There are dice with 4,6,8,10,12,20 sides....... It requires making an assumption which is not neccessarily warranted in the question.
So is question 1 going to be a "haha, I'm misapplying semantics" kind of trick? Because from basic reading comprehension, that is unambiguously 63-17+19=65, but I've got a feeling you'll tell me it's wrong and it actually is just 63-17=46.
huh, guess not.
xD heh
+Poldovico fail
Nope, just an "about 50% of the population has no business staying in school past age 12 and holding everyone else back" kind of trick.
Then again, that's just using your intuition, which is what 25% of adults who got it wrong did. The full equation is
x+17-19=63
x-2=63
x=65
I'm just wondering how you knew to do 63-17+19. A lot of people probably did 63+17-19, which equals 61. I suppose the following thinking might work:"Right now there are 63. There WERE 19 people here in addition, so 63+19. But, there ARE 17 who are here now but weren't before, so 63+19-17."
1. 65
2. 70

What i cant figure out is how people can fail at these questions...
The train started with 0 people, on the first station. And the number 3 is expected to occur 420 times, being 70 times faced up.
i bet, if you do the "question 2" thousands times, you will find most of the results are not 70 rolls.
Lol when i worked it out i thought there be some sort of trick question
I'm 64, and I really AM laughing out loud at your comment, not because it was funny, but because I agree so wholeheartedly with you. The problems were so easy I thought they were trick questions.
exactly,, me too.
same at one I was like there's not enough information and on two I thought it was 420 time since it said expected
that's why some adults had problems with these questions. they were over thinking it.
+DeadOr AliveFan I explained this in another thread. "expected" means "probability" in math. the only way to get this wrong is if the die is not a standard die (meaning it has multiple sides with the same number or if it has more or less than 6 sides)
Question 2 is a horribly worded question. "Dice" is plural. Usually when it is used it refers to a pair (2) of dice. The odds are markedly different with 2 dice as opposed to 1 die.
This seems to be an American English thing. I had no idea some people had ignorantly begun using the word "dice" as a singular form of the noun!
an ordinary dice. an
As I said, horribly worded. You may use dice to mean one die, but it doesn't make it proper usage, and ambiguous meaning in the question nullifies the point of the video.
+Steve Anderson When you ask a question involving multiple dice (or whatever the plural is), you specify the number. If no number is specified, it's safe to assume it's just the one.
I guess you all feel better thinking other people are stupid, rather than thinking the question was ambiguous. I suppose if that makes you sleep better at night, go for it.
Second one is confusing. I assumed "dice" meant a standard pair of dice. If referring to a single piece, it would be better to use the singular "die" or otherwise clarify it is just one piece.
I mean... I am 15 and these are waaaay to easy for me and for what we read in my grade...

..to easy??? Don't you learn to spell these days?
Sometimes you use math terms that I've never heard of, and now you bring us math for 10 year olds. This video was really pointless.
The trick here is that technically "dice" is pleural implying at least two "die" have been rolled. The trick is NOT in the maths but in the grammar.
It's a grammatical error, as the question begins with " *An* ordinary, fair dice". "An" signifies that it's just one die.
Dice is both singular and plural though.
@@Serpinstrix from dictionary.com:
dice [ dahys ] - plural noun, singular die.
Dice is plural, die is singular.
@@ChristopherBurkholder Except I looked it up just now and find...
"dice was once the plural of die, but in modern standard English, dice is both the singular and the plural"
The dictionairy.com is either outdated or just doesn't mention that it's both.
Incorrect. It says "an" so your interpretation would still not make sense grammatically. And "dice" has been an accepted term for the singular for some time now.
Question #2 is a little misleading. Dice is the plural of die indicating a pair. The answer you gave is for a single die. In a pair of dice there are 36 possible ways to roll the numbers 2-12. For example the number 5 can be rolled with four different combinations. They are a 1&4, 4&1,2&3, 3&2. The number 3 can only be rolled two ways. 1&2 or 2&1. Two out of a possible thirty six means one out of 18 times a 3 should show up. Or dividing 420/18= 23.33 times per 420 throws.
I had to check if this was uploaded on April 1st.
This is how I calculated the 1st question:
17 - 63 = 46
46 + 19 = 65
So the answer is 65
that is my solution.
17 - 63 = -46 the teacher would mark 1/2 off for your work being incorrect
@@mushtacular9399 |17 - 63| = 46

Die is singular dice is plural
First question is a trick question. Clearly, before a train can pick up passengers, it has to have staff on the train. But, to "begin", the train would start empty. Therefore, the actual correct answer is zero.
I was like this is so easy... but wait, is there some trick? Triple check my math... This cant be that easy. There must be something im missing...
Then acceptance and bliss of getting the answer correct.
And then a sense of dread about just how stupid mankind is.
these questions were soo easy
Didn't get the 2nd one. I thought it was 420. I forgot about the other numbers. DRATS!!
Same here
-_-
70 easy
The second question is loaded. The question ask "How many times is 3 expected "
The correct answer is anything between 0 and 420. If the dice is truly fair and random there is no way to truly tell how many times it is "expected" to land on 3. It dose not matter if the dice is rolled 1 time or a million the only time you can expect a dice to land on a certain number is if the dice is loaded.
agreed, the amount of times a 3 is rolled with the highest chance of occurring is 70. But the real answer is that it could be anywhere between 0 and 420. although to roll a die 420 times and never get a 3 is extremely unlikely it is still theoretically possible.
What about the conductor?
There were 66 people on the train.
I'm not that smart; all I did was 63-17+19=65.
Same.

why minus 17 & is 19 that left?
+CheeseCake.Luv how did you figured that?!
If 19 people get off the train and 17 people get on, leaving 63 people (??-19+17=63), then all we have to do is reverse that (63-17+19=65).
The fact im 9 and i solved this with ease makes me feel smarter than einstein
Lol the train always begin with 0 person
Can you not understand the first sentence?
You can understand the last sentence!
No conductor?
I agree with your answer. I suppose it all depends on how you perceive the train in relation to its beginning. I see a train with no passengers on it at the beginning of the train's day.
I got them both right, but on the train question I had to make the assumption that "to begin with" meant "to begin (the start of the question) with". Otherwise one would assume that the train began with zero prior to the first person boarding.
