Airlines typically overbook flights because usually several passengers don’t show up. One airline flies jets that seat a maximum of 200 passengers.  With overbooking, it is possible that more than 200 passengers show up to take a flight.  Suppose that the number of passengers that show up are approximately normally distributed with mean 185 and standard deviation 8. Note:  one can obtain the answers easily using the normal distribution excel spreadsheet.   What is the probability that there will not be enough seats on any given flight?  Use 4 decimal places. Hint:  Consider how many people need to show in order for there not to be enough seats.
