1. Determine the probability mass function of the number of passengers(X) who show up for the flight.2. Find the probability that the flight departs with empty seats.3. Calculate the mean and variance of X. Exercise 5.1 Because all airline passengers do not show up for their reserved seat, anairline sells n = 125 tickets for a flight that holds only 120 passengers. Theprobability that a passenger does not show up is 0.10. Assume that the passengersbehave independently.Engr. A. Lun-IN
