An Introduction to Conditional Probability

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.

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.

how to calc. the jack example by using the formula? i have P(J and R)/P(R), which yields 2/13. why is it wrong? thanks

@jbstatistics 2 жыл бұрын

There are 2 cards that are both a jack and red (the jack of hearts and jack of diamonds). P(J and R) = 2/52. P(R) = 26/52. P(J and R)/P(R) = (2/52)/(26/52) = 2/26 = 1/13.

@miguelfonseca1104 4 жыл бұрын

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.

@wardalafef5705 11 ай бұрын

in the red jacks example why aren't we saying that the probability of drawing a jack givin that the card is red would be : (1/13)/(1/2) wouldn't that be the correct representation of the conditional probability law the probability of the intersection 1/13 over the prob of the card being red 1/2 ? can you please explain.

@jbstatistics 10 ай бұрын

The probability of getting a red jack is 2/52 = 1/26, not 1/13. The intersection of "the card is red" and "the card is a jack" is "the card is a red jack".

Why does Conditional Probability divide by the given event, but not subtract? When you describe Conditional Probability with the Ven Diagram, my thought about subtracting event B is reinforced. It seems like I would get the same answer by subtracting.
