Math Problem Statement
A certain airline has 167 seats available for a flight from YYC (Calgary International Airport) to LAX (Los Angeles International Airport). Because people with reservations do not show up for their flight 13% of the time, the airline always overbooks this flight. That is, there are more passengers that have tickets on the flight than there are seats. Suppose the airline has 177 passengers booked for 167 seats. Assume one person showing up for the flight does not affect others who may, or may not, show up for this flight.What is the chance that a passenger with a flight reservation will not make it to LAX due to overbooking? Use four decimals in your answer.

Formulas
X ~ Binomial(n=177, p=0.87)
P(X > 167)
Normal approximation: Z = (X - μ) / σ
Mean (μ) = n * p
Standard deviation (σ) = √(n * p * (1 - p))
