How do you calculate the probability of two independent events occurring together?

Back

For two independent events A and B, the probability of both occurring is P(A and B) = P(A) * P(B).

How do you find the probability of either event A or event B occurring?

Back

For mutually exclusive events A and B, the probability of either occurring is P(A or B) = P(A) + P(B).
