How many times have you heard at the airport : “The plane is overbooked”
To the average person this sounds ridiculous. Why would they sell more
tickets than seats on the plane? The answer to this business practice 
lies within a binomial experiment exhibited by the following fictitious 
problem:

An airline sells 15 tickets for a small plane with 12 
seats. Overbooking is a common practice at this airline since only 80% 
of passengers that book and pay for a flight usually show up. Even 
though tickets are non-refundable, the airline wants to make more money.

N = number of tickets sold
p = probability a passenger shows up
q = probability a passenger does not show up.
