WebbP(A∩B) is the probability of both independent events “A” and "B" happening together. The symbol "∩" means intersection. This formula is used to quickly predict the result. When … WebbProbability of A or B If Events A and B are independent, the probability that either Event A or Event B occurs is: P (A or B) = P (A) + P (B) - P (A and B) In this discussion, when we say "A or B occurs" we include three possibilities: A occurs and B does not occur B occurs and A does not occur Both A and B occur
