WebFrom the above explanation, the P (A∪B) formula is: P (A∪B) = P (A) + P (B) - P (A∩B) This is also known as the addition theorem of probability. But what if events A and B are mutually exclusive? In that case, P (A∩B) = 0. The P (A∪B) formula when A and B are mutually exclusive is, P (A∪B) = P (A) + P (B) Examples Using P (A∪B) Formula WebP ( A B) is the probability of A, given that B has already occurred. This is not the same as P ( A) P ( B. In fact P ( A B) = P ( A ∩ B) P ( B) Given the phrasing about diseases and tests, I am quite confident by P ( A / B) they actually mean P ( A B).
