Sum of probabilities of complementary events is 1. P(A)+P(A’)=1. Example: When a coin is tossed, the probability of getting ahead is 1/2, and the complementary event for getting ahead is getting a tail so the Probability of getting a tail is 1/2. Solution:

We denote the complement of the event E by EC. From set theory, E and EC have an empty intersection and are mutually exclusive. Furthermore E U EC = S, the entire sample space. These facts, combined with the axioms give us: 1 = P ( S) = P ( E U EC) = P ( E) + P ( EC) .
