Question

suppose that E and F are two events and that P(E and F) = 0.4 and P(E) =0.8 what is P(F/E)

Answer 1

Use the conditional probability formula to find P(F|E), which means the probability of event F will occur given the fact that event E already occurred.

P(F|E) = P(E and F)/P(E) = 0.4/0.8 = 0.5

Answer 2

P(F/E) = P(F and E)/P(E) = 0.4/0.8 = 0.5
