How do you find the probability of an event?

The probability of an event occurring given that another event has already occurred is called a conditional probability. Recall that when two events, A and B, are dependent, the probability of both occurring is: P (A and B) = P (A) × P (B given A) or P (A and B) = P (A) × P (B | A)
