(a) What is the probability that the airline can accommodate everyone who shows up for the flight?
P(airline can accommodate everyone who shows up) =
(b) What is the probability that not all passengers can be accommodated?
P(not all passengers can be accommodated) =
(c) If you are trying to get a seat on such a flight and you are number 1 on the standby list, what is the probability that you will be able to take the flight?
P(number 1 standby will be able to take the flight) =
What if you are number 3?
P(number 3 standby will be able to take the flight) =
