Ok, I was looking at some solutions and they dont seem correct. Here is the problem: An airline knows that the probability a person holding a reservation on a certain flight will not appear is 10%. The plane holds 90 people. a) If 95 reservations have been solf, find the prob. that the airline will be able o accommodate everyone appearing on the plane. b) How many reservatiosn should be sold so that the ariline can accomodate everyone who appears for the flight 99% of the time?
