Bayes’ Theorem Problems, Definition and Examples

WebDec 29, 2024 · The problem is as follows, we have 3 cards, - one is blue on both sides - one is red on both sides - one is blue on one and red on the other side. If a card is drawn randomly, what is the probability that given one side red, the other side is blue. One of the answers is 1/2, which seems logical to me as there are 2 blue cards, one is all blue ... WebJun 3, 2024 · Using Bayes' theorem, we get P ( A 1 A 2 c) = P ( A 2 c A 1) ⋅ P ( A 1) P ( A 2 c). The probability that the prize is not in the second door, given that it is in the first one is clearly 1. Hence, P ( A 2 c A 1) = 1. Because the prize is put at random, P ( A 1) = 1 3. Finally, the probability that the prize is not in the second door is 2 3. raymarine s3g
