Probability of an Event The probability of an event, denoted as P(E), is the numerical measure of the likelihood that an event will occur. It is calculated by finding the quotient of the number of favorable outcomes and the total number of possible outcomes. In symbols, n(E) P(E)= n(S) where n(E) is the number of the elements in the event and n(S) is the number of the elements in the sample space. 1.
