11 years old and is still the clearest video i've come across so far. The visuals helped so much. I appreciate you!!
Please continue to post these very clear and concise explanations. These videos are by far some of the most clearest explanations of statistics. Probability of finding a video as this: one in a million.

The pace is always hard for me because the RUclips audience is so diverse. My target audience are those students that are struggling with statistics and I have learned that for a struggling student the pace can never be too slow.
Thank you so much for your positive feedback! Much appreciated.

Appreciate the great feedback. Make sure you tell your friends and classmates about MyBookSucks and like us on facebook to (see the link in the description of the video).
Thanks again!
I think you are referring to when I change the problem starting at about 5:34 in the video. In the second half of the video, I change the problem from P(B) being an odd number to P(B) being equal to 1.
Make sense? If not let me know and try to expand on your question a bit.
Great, I've a Stats exam in a few weeks and you're making my life a lot easier with these videos!
Thank you! I'm taking stats for the first time this year as a senior in high school and most of it comes pretty easy but this is something I was never able to wrap my mind around! This was very helpful for me and I feel so relieved!
This was the clearest explanation of this concept I've seen anywhere. Thank you.
You are very welcome and I do appreciate the feedback. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
Thank You! This is the best explanation of conditional probability I have come across. The Venn diagram and the verbiage "they interset 2 out of 6 times" really drove home the meaning of P(A∩B)
You are very welcome.

The pace and length for me is always a struggle because the RUclips audience is so diverse. Thanks for you input.
This was an absolutely incredible video. Far and very far better than a stats course I am doing.
Super helpful and working step by step is super helpful. Thank you so much for this video!
Many Thanks! Make sure you help me spread the word about the free videos. One thing that helps is if you like MyBookSucks on Facebook (see link in the video description).
You’ve been the first person to get me to understand this. Thank you!!!
I just became the 1000th person to like this video because you, sir, deserve it. Thanks!
Indeed! This is a visual learner's paradise. Very well done! I'm so glad I found this site!
THANK YOU! After numerous searches I finally came across your account! This is the one that made it click!
Great suggestion and it is my plan to have a series of videos on Bayes Theorem. I hope to have one done within the next week or so.
Thank-you so much! I've been in the hospital for a while and I have a lot of school work to do. Most of it is easy but conditionals are super difficult. I've never seen anyone who made math this understandable!
really helps seeing it drawn out and explained step by step like this, really helps thank you!
I was getting so frustrated because I couldn't figure this out but your video was a LIFE SAVER. Thank you so much!
Great example! The first time I have seen a complicated subject explained in very understandable terms.
Love it. Thank you so much. Refreshing my old maths knowledge. You sir, are a legend!
Thank you so much, My teacher taught us this today, and he lost me in the beginning, you made it easier to understand what P(B) and P(A) is. I watched the video twice and I am starting to understand it more and more. Thank you.
You are very welcome. I appreciate questions because it helps me understand what students are struggling with and then I can create right videos.
Great to hear and good luck on your test too! You can do it.
So easy to understand. I didn't feel it was to slow at all, bc I need time to process what you say before you start on something else. great job!
Well thank you very much and I appreciate the feedback. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
you explained this really well and i appreciate that you went slowly, thanks so much!
spent whole night tryna learn conditional probability this video taught it the best
Good question. If you look at the video starting at about 4:30 you will see that I use P(A) and P(A) and the intersection is P(A∩ B) not P(B). Is this what you mean? If not let me know the time in the video that you are talking about.
Great to hear!

You are the best. Man, love your videos, keep it up. You deserve a like and a subscriber. Thanks.
Your teaching process makes me easy to understand.Thank you sir.
Many thanks for your feedback, much appreciated.
I have final exam in the morning, needed refresher, and love the slow pace !
one of best intuitive animated video make probability learning more fun..thak you sir.
Thanks for this! Really helped get my head around the formula issues.
Hi! Thank you. This was so helpful considering the fact that I have been finding stats so difficult.
And thx for actually taking the time to at least go through some of these, and thx for the econ videos they really were super valuable for International Econ class and understanding the trade models.
This has made it much clearer for me, thank you!
i got it finally.......a great help for my CAT preps...thnx prof...
Great videos, they've helped me a lot. I'm very impressed by the illustrations and was thus wondering if you could share what program(s) you've used to make these videos?
That was great and couldn't have come at a better time! Thanks!
Could you do something like this for Bayes Theorem please?
Will do. I'm studying to become a math teacher and find these videos to be of tremendous help ;)
Even better than my teacher.
Precise, to the point, easy to understanding.
How I wish you were my Math teacher:(
Thank you! My teacher couldn't tutor me today & I have my finals tomorrow. Thankfully I saw this video!
Thanks and it is my plan to build examples to help people do better on the GMAT / SAT / ACT, etc.. Good luck on your GMAT too.
Yes, you can use a decision tree to help understand conditional probabilities.
This was amazing!!! I was trying to figure out (the sum is at least 10, given that the sum is at least 9). I figured it out after watching this video!! Thx!
Using the visualization of the dice was very helpful. That alone allowed it to click for me. Thanks!
Thanks for clearing my basics. I am studying after 16 years and preparing for CFA.
Thanks this helped! Your wording of the formula is what made the difference for me! :-)
Wow! Thanks so much for clearing that up for me!!!!!! :) I appreciate your time and effort!!!!!
thank you very much for this video, the best explaination I have watched!
my best teacher ever💯👍🏻 my QUANS teacher sucks!
That is great to hear. I was going to name my company/website/FB page -- MyProfessorSucks but went with MyBookSucks instead :). Make sure you like MyBookSucks on FaceBook (see link in video description). This will help other students with horrible professors find the videos.
Thanks!

U r genius man.. as always thx alot.. Statistis is really fun because of u
Great presentation, thank you!
You are welcome and good luck on your CFA!
Thank you, you made it much more clear.
that's totally amazing
Beautifully explained. Thank you so much! You saved me.....:))
Perfect explanation!
Re-Brushing this for GMAT, very well done. Should give some thought on using actual example from standardized tests.
Thanks! that was very clear. I like the graphics.
Thank you, you,ve made it easy.
Thank you, it's really helpful!
Better than my math teacher... Thank you!
THANKS! Im seriously studying this before my exam in 2 hours!! LOL
Luis Mendez So.. you were "partying more studying less" If you get a chance could you please like our FB page. www.FaceBook.Com/PartyMoreStudyLess It will help others find the videos.
Good luck on your exam, you can do it!
statisticsfun this video is very useful! thank you very much.
Luis Mendez for me 15 minutes...
me
Great to hear... maybe you could send a link to your teacher :)
Thanks! Helped me a lot!
While I can't be your teacher, I can post videos for you. And I do call myself the "professor of the universe" :)
This was lovely... I thank you i have aa horribble professor aand this helped sooooo much!
Hi, Thank You SOO MUCH for your work!! Its very clear, especially with the animation. Brilliant idea. Can you just explain to me why the P(A intersection B) has a denominator of 6, in the second case? Thank You
Thank you very much! so helpful!!!
Thank you so much. I try to use 21st Century Tools perhaps that is the difference.

Thank you for simplifying probability for me 😊
You are very welcome.
thanks for sharing the knowledge
Thank you very much! This helped alot!
you are a great person.
+statisticsfun Nice presentation, especially the visual aids :>
Just a minor nitpick: it would be nice if you included the 4 and 6 dice outside the Venn diagram, for completeness of the sample space. Then it would be easier to see where the 6 in the denominators comes from. It is a bit confusing when there's a 6 in the denominator, but one can see only 4 possible dices on the diagram.
Also it would be nice to show how the "|A" shrinks the sample space to just the P(A) circle on the diagram. I see in the comments that there were some people who were confused by that. Showing that the "|A" part makes the sample space to choose from smaller - or throwing the impossible cases out the window in that matter - should make things easier to understand.
Thank you! Super helpful. liked and subsciribed.
You sound like the guy from OwnagePranks... nice video tho :)
Alisha Daswani I have heard that from a couple of people now. Interesting. Hopefully you will like, share, subscribe, If you get a chance could you please like our FB page. www.FaceBook.Com/PartyMoreStudyLess
It will help others find the videos.
Who knows ?
Ownage maths prank ?
Haha
I don't have anything on Bayes yet, but I plan on creating something in the next few weeks.
thank you so much you made my day
great example. thank you.
