WebbTo find: The probability of getting a 2 or 3 when a die is rolled. Let A and B be the events of getting a 2 and getting a 3 when a die is rolled. Then, P (A) = 1 / 6 and P (B) = 1 / 6. In this case, A and B are mutually exclusive as we cannot get 2 and 3 in the same roll of a die. Hence, P (A∩B) = 0. Using the P (A∪B) formula,

WebbTHEOREM: the union of of events. The probability that either A or B will happen or that both will happen is the probability of A happening plus the probability of B happening less the probability of the joint occurrence of A and B: P(A∪B) = P(A)+P(B)−P(A∩B) Proof.
