WebbGiven two events A and B, the union of A and B, written A∪B is the event containing all sample points in A, B or both A and B. On the other hand, the intersection of A and B, written A∩B, is the event containing all sample points in both A and B. The addition law can be used to calculate the probability of the union of two events.

Webb24 apr. 2024 · If A and B are any two events, disjoint or not, then the probability that at least one of them will occur is P(AorB) = P(A) + P(B) − P(AandB) where P (A and B) is the probability that both events occur.
