What is the formula of probability of an event?

P(A) = n(A)/n(S)

P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.

How do you find the probability of two events?

To determine the probability of two independent events, and , both occurring, we multiply the probabilities of each of the two events together: P ( A ) × P ( B ) = P ( A a n d B ) . In some cases, the outcome of one event affects the outcome of a second event.
