(A ∩ B) – can be easily calculated if the events are independent of each other by multiplying the two probabilities P(A) and P(B) as shown below: WebEvents A and B are called mutually exclusive if they cannot both occur, that is, P (A and B) = 0. In this situation, P (A or B) = P (A) + P (B). Events A and B are called independent if the occurrence of one event has no effect on the probability of the other event occurring. In this situation, P (A and B) = P (A)*P (B).
