Select term: Conditional Probability. The probability that event A occurs, given that event B has occurred, is called a conditional probability. The conditional probability of A, given B, is denoted by the symbol P(A|B).
If P (B) = 0, then the simple definition of P (A | B) is undefined. However, it is possible to define a conditional probability with respect to a Ï-algebra of such events (such as those arising from a continuous random variable).
