Conditional rule of probability

WebLet's look at some special cases of conditional probability: When A and B are disjoint: In this case A ∩ B = ∅, so P ( A B) = P ( A ∩ B) P ( B) = P ( ∅) P ( B) = 0. This makes... WebThe multiplication rule is used to find the probability of two events, A and B, happening simultaneously. The general formula is: ... Conditional Probability. Conditional probability is the probability of one event occurring, given that another one has already occurred. We can represent this with the following notation:
