(1) What is the probability that two successive planes selected at random will arrive within 5 minutes of one another? (2) What is the probability that two successive airplanes arrive more than 6 minutes apart? (3) If Tony arrive at the airport just in time to see a plane landing, how long would he expect to wait for the next arrival.?
