HANSEN ©20201 University of Wisconsin Department of Economics December 16, 2020 Comments Welcome 1This manuscript may be printed and reproduced for individual or instructional use, but may not be printed for The conditional probability is found by dividing the joint probability by the unconditional probability, Pr[B] for the given event. This formula can only be used if the appropriate probabilities are known: Pr[A and B] and P[B].
