Let's have two events: event A and event B. Define probability that event A happens P(A), and event B happens P(B). Also define that A and B happen simultaneously as P(A, B). If the event A is statistically independent of the event B then

P(A, B) = P(A)*P(B).

Also based on Bayes formula,
P(A | B) = P(B | A).P(A)/P(B)
