Calculating probabilities regarding seating on an airline.

Eagle airlines' planes hold only 15 people. Past records indicate that 20% of the people making a reservation do not show up. We will assume that all reservations are independent; that is each reservation is for one person and these reservations are made independent of one another. Suppose that Eagle Air decides to book 18 people for each flight.

1. Determine the Probability that on any given flight, at least on passenger holding a reservation will not have a seat?

2.What is the probability that there will be one or more empty seats for any one flight?

The following shows the process of calculating the probability that seats on an airplane will be available or unavailable. Mean and standard deviation of the variable are provided as well.
