I spend 2 hours every week in a biostats class feeling like my brain is mush because I can't understand anything. Then I come to this channel and I'm like "oooooh, I get it!" At this point YT is my teacher because I can't for the life of me understand why my biostats lectures are so complicated.
14:00 He should consider x= 0 as that is also possible, which if we employ the formula, would be 0.75^30 which would be an extremely small number. It would logically make sense, usually we would have a number closer to 25% taking algebra, the chances that 0% take it from a samoke is highly unlikely BUT possible....

You have a point. P(0) =~ 0.000178... in this case. P(1) =~ 0.00178... which is an interesting correlation. This is because, P(1) = (30 * 0.25) * 0.75^29 P(1) = (7.5) * 0.75^29 P(1) = (10 * 0.75) * 0.75^29 P(1) = 10 * 0.75^1 * 0.75^29 P(1) = 10 * 0.75^(1+29) P(1) = 10 * 0.75^30 And P(0) = 0.75^30
Thank you so much, my professor brushed over this lesson, gave us the formula without explaining ANYTHING, didn’t answer any questions, and told us to drop the class if we didn’t understand. I was having a panic attack but this video really helped me out. I guess this channel will be my professor for the rest of the semester….

What kind of teacher is that
thank you so much. i wish i could've found this channel in my high school days. always thought statistics was hard but after watching several videos right now as I am doing forensic statistics, I'm realising how easy it is. Sending you love, light and positivity for lack of tangible gifts!
As someone going back to college for a geoscience degree after 10 years in business management this was SO helpful! I have taken 4 or 5 classes in statistics over my life so far, but it's been so long that I completely forgot how this equation works! Also, the refresher on fractorials was MUCH appreciated!
I really enjoy and appreciate your math lessons. Watching your 20-minute math video helps me understand faster than a 90-minute studying in math class. Thanks again for your lesson.
for Problem 3 b) we need to also include P(0) . since there could be 0 students taking algebra which is also less than 5.

@@yarachesu2604 That is not a valid point since we do not know exact total no. of students in the high school. Say that there are 200 students in the high school XYZ. Then total no.of students taking algebra will be 50(25%). So, other 150 will not be taking algebra. So, since the 30 students are chosen randomly, there is at least a small chance that all 30 are selected from that remaining 150. So, there will be a small probability for p(0) which is actually 0.018%

I credit you for getting me through college level business statistics. THANK YOU!
I don’t know how but your way of teaching is magical. You helped me understand this concepts really easily while one week of lectures couldn’t make them clear. Thank you so much. I wish all my teachers taught like you do.😊
You are really saving my life right now, i could not understand 5 pages of Statistics for Data Science textbook, nor 2 hours of lecture reading slides, 10 minutes into your video am able to solve all the questions. Your work is appreciated. Thank you

You are one of the best teachers I've ever met in my life. Thanks to your help, I am now studying in Stanfford College's Engineering Department.
Amazing learn this more than what I’ve learnt in lecture! Could you please do a video on approximating binomial probability using normal distribution as well, with the use of continuity correction? It would help me a lot! All in all, a big fan of yours!
I really think this type of online teaching is the future, so easy to understand and saves a lot of time!
I really appreciate these videos. You explain everything so well making it easy to understand. A lot easier to understand then my book.
This was easier to learn than my lecturers lessons ha!
Thanks a million, Sir, for this incredibly easy to understand video on a dauntingly confusing concept. You saved my life.
these 20 minuets were way better than the 3 hours i have spent in lectures trying to understand this god bless you!
Thank you so much I finally understand binomial distribution
Firstly, thank you SO much! I have tried tutoring and have been plugging in searches throughout Google, Khan Academy, and KZread for help with solving this type of equation (example 2). Statistics is a huge downfall for me. I want to cry a little, with relief. This video helped significantly. Oddly, this video was one of those random ones from autoplay. So, this may have been "divine intervention", which I am (again) so grateful for.
So descriptive. You're honestly amazing !
Super helpful for someone re-learning this content to help a student in high-school algebra. Thank you for sharing.
Just in time for my stats class this summer! Thank you so much JG!
When I begin to make money, you’d be one of the people I would like to give a little something to show my appreciation Thank you Mr Organic Tutor for always making things easy to learn 🤗
Amazing! Keep up what you do.
You are a life savior for me .I wish I could find this channel before. Thanks for your every single video by which I learn today a lot of things
I am a student of IIT...The most prestigious institute in India...I am only paying over there to know the syllabus...I learn those topics from you...Thank you so much....The way you have learned these topics must be the hard way...

Speechless , simple short and clear 💯
That is by far the quickest way I have ever seen someone explain the formula for standard deviation. I kept doing by √(mean of squares - square of mean) and that took ages.
Hi, Please kindly explain question 3(b)! I thought there is a possibility of picking none on those doing algebra on less than 5 students, making P(0)+P(1)+P(2)+(P3)+P(4)= P(X
Why we didn't consider P(0) in the last question when we calculate P (X
