I have a problem working out the answer to this problem using the binomial formula.
Assume an airline operates a short haul flight form Edinburgh to Manchester, there are 16 seats. Experience shows that 15% of people are a 'no show' so they start taking bookings for 20 people.
Using binomial principles we have 20 'trials', P(1 no show) = 0.15, they are all independent.
P(3 no shows) = P(0 no show)+ P(1 no show) + P(2 no shows) + P(3 no shows)
However I cannot seem to get the answer by using the formula method.
Can anyone help??
