WebThe symbol "∪" (union) means "or". i.e., P (A∪B) is the probability of happening of the event A or B. To find, P (A∪B), we have to count the sample points that are present in both A and B. So is P (A∪B) = P (A) + P (B)? No, because while counting the sample points from A and B, the sample points that are in A∩B are counted twice.
