WebJul 3, 2015 · Formula for compound probability P (A or B) = P (A) + P (B) – P (A and B) where A and B are any two events. P (A or B) is the probability of the occurrence of atleast one of the events. P (A and B) is the probability of the occurrence of both A and B at the same time. Mutually exclusive events: We use the following formula to calculate this probability: P (A B) = P (A)*P (B A) / P (B) where: P (A B): The probability of event A, given event B has occurred. P (B A): The probability of event B, given event A has occurred. P (A): The probability of event A. P (B): The probability of event B.
