The Addition Law of Probability - General Case If two events are A and B then P(A∪B)=P(A)+P(B)−P(A∩B) Of course if A∩ B = ∅ i.e. A and B are mutually exclusive, then, P(A∩ B)=P(∅)=0and this general expression reduces to the simpler case. This rule can be extended to three or more events, for example:
