The conditional probability of A given B is deflned to be P[AjB] = P[A\B] P[B] One way to think about this is that if we are told that event B occurs, the sample space of interest is now B instead of › and conditional probability is a probability measure on B. P(A)  =  1/3, P(B)  =  1/4 and P(C)  =  1/5. Joint, Conditional, & Marginal Probabilities 4 Conditional probability in mathematics allows for calculating the chance of an occurrence.
