WebA and B are called complementary events. This may be denoted as: P (A ’ ) = P (B) (recall in sets that A ’ is the complement of A) P (A) = P (B ’ ) We can generally state that: P (A) + P (A ’ ) = 1. Example: A number is chosen at random from a set of whole numbers from 1 to 50. Calculate the probability that the chosen number is not a ... WebThe Probability of the Complement. In any experiment, an event A A or its complement AC A C must occur. This means that P (A) + P (AC) = 1 P ( A) + P ( A C) = 1 . Rearranging this equation gives us a formula for finding the probability of the complement from the original event: P (AC) = 1 −P (A) P ( A C) = 1 − P ( A)
