I was unreasonably happy to see that the blob finally made a shot at the end
:)

Same! :)
:]
:3
This is literally our math subject rn. Thanks man.
Same
This one's for you
@@PrimerBlobs 🙏
@@PrimerBlobslmao thanks, I actually learned the stuff in the video in January and it's so nice when I look at the formulas and understand them
E
The return of the king
Yeah
Biggest W of June so far
E
Every his video is return?
This has no reason to be as good as it is, thank you, I finally get it
No matter the subject, I’ll watch these all the way through, even if I won’t learn it for years.
E
You're learning by watching! No need to wait for a formal class.

I personally miss the evolution/economic vids. I'll still watch these, but those are what brought me to the channel.
Me too, me too. There's an econ one cooking currently.
let the man cook
Same! :(
@@PrimerBlobs thanks, I'm looking forward to it.
@@PrimerBlobs good to hear
Primer is the only educational TH-camr I watch cause he makes it fun
I'd recommend a few:
1. 3Blue1Brown has similar math visualizations over a number of math topics.
2. Kurgesagt has really interesting animations over many topics, including science, climate change, space, and aliens.
3. Veritasium shows sciencey things in cool ways.
4. TedEd has short animations on a variety of topics, like science, mythology, fiction, history, and social studies.
5. MinuteEarth has fun, short animations about the Earth, nature, and related science topics.
6. MinutePhysics has short animations about physics.
This is by no means an exhaustive list, but I watch these channels more than others. For shorter videos, try starting with TedEd, MinuteEarth, and MinutePhysics. The other channels have slightly longer, more in-depth videos.
@@spmagic9083thanks, i was about to write the same. It's so cool that this form of education connects us all even though we don't know each other.
What do you mean he makes it fun? Mathematics is fun. What he does is very clean visuals and is quite good at it. That's why I watch, even though I learned all of this many years ago.
E
Not only does he EXPLAIN with absolute eloquence and clarity, but the care he puts into the animations is remarkable.
I just love the presentation and explanations in these videos so much, it makes the entire lesson so much more engaging

@@EEEEEEEE E
By now I've done 4 semesters of statistics classes but none of my professors was able to explain this concept as easily understandable as this video.
For binomials and the choose function there are really nice ways to build intuition, experiments to derive rules like in this video.
However, in combinatorics you often care about slightly more complex things, where you have more classes than yes/no and dependencies between objects.
For example, for a given graph, how many ways are there to label the nodes such that the graphs are isomorphic?
When I learned this and taught it to other students I always had the feeling that this was one of the things for which you need a good understanding of the problem to solve it as there is no go-to formula or procedure to solve those. The only way that seemed to work is to solve different instances over until it clicks
tl;dr: I found teaching combinatorics really hard.
@@ensiehsafary7633also, the time/resources are no where equal to what a professor has.
Because you're expected to explain it to yourself, using different sources. THAT IS THE VERY ESSENCE OF UNIVERSITY
@@47Mortuus that's not how math classes tend to go. It's not like it was a research paper topic.
@@anthonynorman7545 stay ignorant :)
The encouragements to pause and think through things are _vital_ to get people to actually _understand_ and not just watch the video and forget immediately.
Very well done all around!
Chance of your team's Yasuo actually being good: infinitesimal
Great video as always
That LoL reference came completely out of nowhere.
Yeah I was way too surprised by that lol
Yeah, Yasuo teammate is the last blob in the video.
@@TheAlexN1305 Nah, don't be mean to the blob
i clicked on this video from the recommended sidebar while watching a league video so this actually was extremely fitting hahaha
Can black blob with sunglasses become a recurring character? I think his character arc involving missing all the shots was very interesting

This isn't over-explained at all. This is the kind of explanation I've been looking for for so long!
its a good *year* when Primer uploads
hey
"your team's yasuo actually being good" is a reference i didn't expect at all, love your videos, was super excited to see this video in my sub box
Oh how I have missed the blobs engaging in simulations. So nice to see a new video.
As always a pure delight to be able to learn and be entertained at the same time. All education should be this way.
4:28 I love the enthusiasm of the blob on the left who keeps on trying to score.

@@EEEEEEEE mate, a E has escaped your cage
@@EEEEEEEE bro is spamming E on all videos
I hadn't noticed this, thanks!
I wish I'd had this when covering counting problems! Your explanations and visuals are so much easier to comprehend than the lectures I read.
He should be the next channel to be featured in schools!
one day in the future, this is gonna be played in a classroom for a maths class, and your gonna make a lot of people laugh and understand this a much better and get their foot into the doors of stats and further stats. amazing vid
I'm so glad you did this video cos just the other day I was cracking my head on a similar problem and couldn't make out how binomial coefficient work on my own, thanks a lot for making it crystal clear. Great job, as always!
This is a wonderfully succinct and comprehensive explanation of this topic that actually covers the reasons *why* the formula was constructed the way that is, not just how to use it. My math-teacher mom and I approve.
I love the rest of your bio, econ, and math stuff, too. Here’s hoping the algorithm feeds this to more people!
The blob at the end is just footage of me trying to play basketball
I can not believe it. I love your videos so much. I actually discovered your channel this morning. When I entered it and saw your last video was from ten months ago I thought you wouldn't be doing more videos. So the fact that on the same day I found you, you put a video makes me so happy. Keep it up, the blobs are the best
I love these blobs! And the topics in your videos are covered in such an easy-to-follow fashion. Thank you so much for making them!
15:12 I cheered so loud congrats buddy you did it
You can’t imagine how happy I was to see you coming back! Your videos are so good! Keep going! ❤
Oh wow I was just looking at your channel and wondering when you would post next, I'm glad to be able to watch a new video of yours, they're always great!
I have been waiting for more videos, thanks for posting!
Just learned this in class, and you helped me understand this so much better. Thank you so much!
No puedo explicar cuanto hubiera querido tener este tipo de explicación en la época de estudiante. Excelente!
The blobs are adorable! Definitely going to ask for a plush or two this Christmas And seeing that this channel doesn’t overload one with videos, I subscribed pretty dang fast.
This is great timing! I have my maths A level mock in a few weeks, and I'm not the biggest fan of stats, so this is really useful for brushing up on it.
I love your videos, every time you release one it’s like everything else freezes and I half to watch your video. Keep up the good work
I'm abot
As someone who just took stat, this was a really nice reminder of the logic behind everything and made me actually think about math for the first time in a few weeks. Fantastic video!

So glad you brought this equation back to talk about. One of my favorite videos you've done is the coin flip one and I like using the binomial distribution formula when I can, but always forget what the values would stand for and I'd have to go to the linked video to remind myself. This will be much easier to find and sit through.
It was amazing to watch the whole content. super high quality, kudos to the amazing team and hard work behind it
my immediate thought when watching this, given the free-throw example from basketball, is calculating the odds of any given baseball pitcher throwing a perfect game (a game where not a single opposing batter gets on base over all nine innings) based on their WHIP statistic (walks and hits per inning pitched)! very cool video, as always :)
This is quite good. If I still taught Prob and Stats, I'd share this in my class.
How did you reply to this 1 day ago???
Hold up how did this comment become 1 day old but the video isn't an hour old
wtf how did you comment one day ago the video was made 38 seconds ago
@@loopeater8338 Video was unlisted before releasing, and they had the link to view it.
@Don't Read My Profile Picture wasn't planning on it
I love these videos. You have a great way of explaining things in a very intuitive way. I especially liked the demonstrations for calculating the binomial coefficient. Showing that the Nth blob added to the list can be inserted in N different positions really helps solidify why ordering is calculated using factorials*. And then using that to remove the duplicates from each group made a lot more sense than just trying to memorize the formula.
* The way I usually think about ordering is if I have N items, then the first one in the list could be any of the N items, then the second could be any of the remaining N-1 items, then N-2, and so on until the last one.
Easily the best description of Binomial distributions and, most importantly, the fundamentals that support it.
Fantastic! I’ll be sharing it with my son. thank you 👍

I’ll keep this in my pocket for when I have my statistics class this autumn
Such impressive visualizations. The little extra efforts like making the numbers move or blink to guide the eye are very helpful.
Love your videos.Keep up the good work.
I will try. >_
Absolutely love your content. Almost yelled out "BLOB GUY HAS A NEW VIDEO" when I saw this in my feed earlier.
I can only assume how much effort goes into these videos, but I sincerely hope you'll keep making them - they are truly awesome.
The last line really hit me and made me subscribe. Love your videos. Keep going!
On Friday I just had my Uni Probability exam and part of what we learned is exactly this. Awesome video and explanations, as always actually!!
If Primer uploads a video, you know it's a good day

@@molybd3num823 sorry, autocorrector
This isn't overexplained, this is the explanation I wish I'd gotten in school. Thx 👌
Very Few Times I have seen someone explaining such concepts with such clarity.Thanks, A lot
Exactly the explanation I was looking for! Great video!
Whenever Primer uploads. It’s a good day.
I wish this video came out like 5 years ago when I had to learn this
these videos really cement in the fact that i prefer statistics/combinatorics to things like calculus. i struggle to pay attention to and care about what goes on in my calculus classes, but i willingly watch, stay engaged with, and seek out more content focusing on this sort of stuff. thanks for reminding me that not all math is nightmarish 😉
Beautiful! Oh this is perfect! I tutor genetics and have some students that struggle with statistics, and I am going to tuck this into my tool box! Thanks for making the math pretty, well chewed, and easy to digest.
I've already used some of your other videos with positive feedback, I just hope the next wait for a new one isn't as long as the last.
A única coisa ruim desse canal é que ele deveria postar vídeos todos os dias. MUITO BOM!
Keep up the good work!
Thanks, Sara!
OMG it’s Primer
I really enjoy the style that you present in and would love to see more videos. I love getting your notifications.
Always glad to see another Primer vid!
I litteraly just learnt this exact thing for the first time in my maths lesson yesterday!! What are the chances!?
100%
@@PrimerBlobs Did you use the formula to get to that conclusion 😅

Beautifully explaine dand visualized. I love how in detail everything is explained. Thanks!
This video is such an amazing tool to understand the subject. The visuals are just perfect to support the theoratical part❤ Yet again amazing job!!
I always watch primer, regardless of the subject, because if I do not know it its a great opportunity to learn it, and if I already know it its still a great opportunity to learn about communication and didactics. I always end the video feeling smarter and that keeps me engaged. Thank you very much for the effort in making these as easy-to-understand as possible!
I recently finished alg 2 and we learned this but skipped over most of the explanation and went right to the combinations and permutations, it's nice to learn more about what makes these formulas work.
This is so amazing! The graphics are super well done too. Thank you Primer!
Thank you for that great video, your videos always make me understand those topics deeper.
You make this so understandable and clear! Keep up the good work man
Brooo... It's Primer! He's back!
Jokes aside I love your videos man, hope to see more of you soon 👊
what a amazing video, the best class I've ever watched about binomial distribution along with this clear and well-done animation transformed this simple 15min video into a masterpiece, congrats 👏🏼👏🏼👏🏼
Fantastic video! The quality has really gone up recently!
A statistics video from Primer right as I am about to start my Stats this semester and I love it!
I love these videos you make, they are instructive with a fun way to learn.
Yay! Finally another post! I love your videos, they're educational but in a way that entirely makes sense and is also fun to watch because of the animations. :)
Thanks! This was something I studied earlier in the year, was really interesting to see it explained again, and quite well too.
Perfect timing for my A-level Stats paper in two days time!!!
Great video. Really well explained!
One of the things i think should always be brought up when mentioning Pascal's triangle, is that you can describe it by multiplying odds as if it was a polynomial.
For example:
Lets say you had that you could either make a shot or miss it. This could be described as (X + Y), where X is a missed shot, Y is a made shot.
If you make 2 shots, it would look like (X + Y)^2 = 1X^2 + 2XY + 1Y^2. This holds with n shots, or (X + Y)^n.
You may also notice that the expanded polynomial is also pascal's triangle, which is how we can easily calculate the triangle in the first place.
This also works with more than 2 distinct outcomes, like (A + B + C +D)^n.
It’s a good year when primer upload ❤
I would have had less trouble with combinations and probabilities in highschool if this video existed back then. Very nice and intuitive explanation.
Thanks for that! I am huge fan of your videos and the binomial distribution :)
holy moley I never learned about this in school, but I've occasionally been interested in calculating probabilities for certain things, and my eyes glazed over when I looked up binomial distribution, but seeing it here, it's gotten a LOT easier to understand... nice video!
He came back!!! 🎉🎉🎉 I really enjoy this videos.
I've had combinatorics in high school, and we did "learn" the formula there - as in, "this is the formula, you need to remember it because it works". Thanks to this video, I've finally understood where the formula comes from. Thanks!
I do a lot of statistics for work, and I still watched this video because a) always great to review the fundamentals and b) your videos are just that good.
I absolutely loved this! You should do one on geometric distribution and normal distribution!!
Your videos don't teach me anything new but they are so well made I want "the algorithm" to know this is good content so I watch all the way to the end, give it a thumbs up, and even interact with it further by leaving a comment like this one!
Seriously, though, your videos are always really good and you deserve to know that.
This was really cool! I wish you had mentioned how dividing factorials is super easy too, to simplify that big ratio you showed near the end
Literally did my final math exam (12th grade) today and I did revision for analytical combinatorics covering this exact subject! I'm surprised how well I understood this video. There were a few aha moments where a couple things at a time slotted into place :)
It really makes sense now why you subtract in the parentheses before the factorial. Thanks for the video!
You're back! One of the best math channels on YT
So glad to see your video after sooooo long
Where have you been for a whole year 😭 I missed you so much, always appreciated your way of teaching. Keep it up bro 💯 *Your team's Yasuo actually being good 😂
I am supposed to learn this for school and my teacher unfortunately isn't the best when it comes to explaining, so it is very nice to have you make a video on this topic.
Thank you for this, I always struggled with binomial distribution but this video makes it very easy to understand
Complimenti! Un video ottimamente realizzato.
I was really missing these videos!!
Astonishingly beautiful 3-D diagrams, as usual!
It’s always a great day for a Primer video!!!
Just had a test about this last week, awesome video, would have loved to see it back then.
