WebbThe probability of the union of A and B, P (A or B), is equal to P (A) + P (B) - P (A and B) = 3/5 + 2/5 - 6/25 = 1 - 6/25 = 19/25 = 0.76. For another example, consider tossing two coins. The probability of a head on any toss is equal to 1/2. WebbIf A and B are mutually exclusive events, then the probability that at least one of the two (equivalent to one or the other or both) will happen is P ( A U B) = P ( A) + P ( B) If A and B could both occur, then the probability that at least one of the two happens is P ( A U B) = P ( A) + P ( B) – P ( A∩B)
