WebConditional Probability is a mathematical function or method used in the context of probability & statistics, often denoted by P(A B) to represent the possibility of event B to occur, given that the even of A already occurred, and is generally measured by the ratio of favorable events to the total number of events possible. The probability of conditional … WebIf A and B are two events defined on a sample space, then: P(A AND B) = P(B)P(A B).
