WebbTwo events A A and B B have probabilities given below: Pr[A] = 1 3 Pr[B] = 1 2 Pr[A∪B] = 5 6 Pr [ A] = 1 3 Pr [ B] = 1 2 Pr [ A ∪ B] = 5 6 Are events A A and B B mutually exclusive or not? Answer In general, if we do not know anything about the events A A and B B. It is always correct to estimate Pr[A∪B] ≤ Pr[A]+Pr[B].

WebbThen we can apply the appropriate Addition Rule: Addition Rule 1: When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event. P (A or B) = P (A) + P (B) Addition Rule 2: When two events, A and B, are non-mutually exclusive, there is some overlap between these events. The ...
