Two different airlines have a flight from NYC to LA that departs each weekday morning. Let E = event that the first airline's flight is fully booked and F = event that the second airline's flight is fully booked. Suppose that P(E) = 0.6, P(F) = 0.7, and P(E n F) = 0.5. 1. Given that the first flight is fully booked, what is the probability that the second flight is also fully booked? 2. Are the two events E and F independent of each other? Explain. 3. What is the probability that neither flight is fully booked
