Mathematics Learning Centre, University of Sydney 1 1 Introduction Calculations in probability theory often involve working out the number of different ways in which something can happen. Then, we need to find the probability of P (A ∩ B). It provides examples of using the addition rule to calculate the probability of events composed of two outcomes. This lesson deals with the multiplication rule. P (A ∪ B ∪ C) = P (A) + P (B) + P (C) − P (A ∩ B) − P(B ∩C) −P (A ∩C) + P(A ∩ B ∩C). 4.
