If A and B are independent events, then the probability … WebThe concept of independence applies to any number of events. For example, three events A, B, and C are independent if P (A ∩ B ∩ C) = P (A) · P (B) · P (C). Note carefully that, as is the case with just two events, this is not a formula that is always valid, but holds precisely when the events in question are independent.
