An airline estimates that 91% of people booked on their flights actualy show up.
If the airline books 79 people on a flight for which the maximum number is 77, what is the probability that the number of people who show up will exceed the capacity of the plane?
-----
Binomial Problem with n= 79, p = 0.91, 78<= x <=79
------
P(78 <= x <= 79) = 1 - P(0<= x <=77)
= 1-binomcdf(79,0.91,77)
= 0.0051..
