Suppose that past experience shows that about 11% of passengers who are scheduled to take a particular flight fail to show up. For this reason, airlines sometimes overbook flights, selling more tickets than they have seats, with the expectation that they will have some no shows. Suppose an airline uses a small jet with seating for 30 passengers on a regional route and assume that passengers are independent of each other in whether they show up for the flight. Suppose that the airline consistently sells 32 tickets for every one of these flights.A. Describe a random variable X. Explain carefally what distribution can be use and what are a are the values of the parameters? B. On average, how many passengers will be on each flight? C. Find the probability that at least 40 seats will be filled. D. How often will they have enough seats for all of the passengers who show up for the flight?
