An introduction to conditional probability, pitched at a level appropriate for a typical introductory statistics course. I work through some simple examples in this introductory video, and a I briefly touch on the concept of independence in an example at the end of the video. I work through more examples (some a little harder) in my conditional probability example problems video: • Conditional Probabilit... .

I failed probability last year and retaking it this year. Your explanation of Pr (A|B) using the Venn diagram is so absurdly logical I am floored. It's 100 times easier to see than trying to use numbers and algebra. I've yet to learn how to understand concepts in this 'different' way.

Best explanation ever had. I love when he says, please do me a small favour and don't memorise the formula. That's how every teacher should be ❤

Your explanation of conditional probability using the Venn Diagram just blew my mind. So much easier to grasp the topic when you get an intuitive explanation of the topic.

Thank you so much for making this video! I just started learning statistic on Coursera, but the teacher there makes it complicated and way too difficult to understand. And then I found your video! You are a life saver. Keep up the good job!

This is what i had at first: S= (0,1,10,100) A=S1(10,100) B=S2(10) P(B/A) = P(A n B)/ P(A) = (1/4)/ (2/4)=1/2 =0.5 What I did above works if an only if they (payouts) do have the same probabilities.... but the probabilities differ according to the payout. Thanks alot sir

@miguelfonseca1104 4 года назад
you did well, the division part of the conditional probability really threw me off, but the way you explain just made me realize in non-conditional probability, the probability in a sense has a denominator of 1 which signifies "from the whole sample space", when you add given, you must divide to specify its a part of which (partial whole). Thank you. Other videos dont make that clear.
