When A and B are independent, P (A and B) = P (A) * P (B); but when A and B are dependent, things get a little complicated, and the formula (also known as Bayes Rule) is P (A and B) = P (A B) * P (B). The intuition here is that the probability of B being True times ... 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.
