J 2 10. Airlines routinely overbook flights to help lower the number of empty seats on their airplanes in order to increase profits. In the year 2005, the no-show rate was estimated to be 12%, with 88% of passengers with tickets actually showing up to take the flight. Suppose an airplane has 25 seats, and that the airline has sold 27 tickets. What is the probability that there will not be enough seats? 11. Referring to the no-show rates from Problem 10, out of 27 tickets sold, what are the mean and standard deviation for the number of people that show up to take the flight need answer for 11!
