Question description

You take a trip by air that involves three independent flights. If there is an 71 percent chance each specific leg of the trip is on time, what is the probability all three flights arrive on time? (Round your answer to 3 decimal places.)

Let P(X) =0.55 and P(Y) = 0.35  Assume the probability that they both occur is 0.20.

 What is the probability of either X or Y occurring? (Round your answer to 2 decimal places.)
