Question 612518
Consider a low cost airline operating a 120-seat plane. The company typically sells 125 tickets on the flight since not all passengers usually show up for their reserved seat.
The probability that a passenger misses his/her flight is 0.10 and we consider that all passengers behave independently.
--------
Binomial Problem with n = 125 and p(shows up) = 0.9
P(0<= x <=120) = binomcdf(125,0.9,120) = 


(a) What is the probability that every passenger who shows up for the flight can get a seat? 
------
P(0<= x <=120) = binomcdf(125,0.9,120) = 0.9961
