Because not all airline passengers show up for their
reserved seat, an airline sells 125 tickets for a flight
that holds only 120 passengers. the probability that
a passenger does not show up is 0.10, and the passengers
behave independently.
(a) What is the probability that every
passengers who shows up gets a seat?
課本的解答是 0.9961

懇請指教
