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.
