What is compound probability?

Back

Compound probability refers to the probability of two or more events happening at the same time. It can be calculated using the multiplication rule for independent events or the addition rule for mutually exclusive events.

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

Back

To calculate the probability of two independent events A and B occurring, multiply the probability of A by the probability of B: P(A and B) = P(A) * P(B).
