WebIn this case, the probability of A intersection B formulas will be: P (A∩B) = P (A B)P (B) or P (A∩B) = P (B A)P (A) Here, P (A B) = P (A given B) P (B A) = P (B given A) Solved … Web1 If events A and B are mutually exclusive, what is the probability of the intersection of their complement? I reasoned that P ( A c ∪ B c) = 1 1 = P ( A c) + P ( B c) − P ( A c ∩ B c) P ( A c ∩ B c) = P ( A c) − P ( B c) − 1 However, I also saw in a recent post that P ( A c ∩ B c) = 1 − P ( A) − P ( B) which is not equal to what I got.
