An airline knows that, on average, the probability that a passenger will not show up for a flight is 6%. If an airplane is fully booked and holds 300 passengers how many seats are expected to be empty? If the airline overbooked the flight by 10 passengers about how many passengers are expected to show up for the flight? Justify your answer.

Question

My answer: 18 seats are expected to be empty
If the airline overbooked by 10 passengers then I believe that 310 passengers would be expected to show up for the flight

Are my answers correct?

Answer 1

your first part is correct, but I disagree with the 2nd part.

If they overbooked by 10, that would mean 310 booked on the flight
6% of 310 = 18.6
so I would say that 19 would not show, leaving 291 to show up

Answer 2

Hello Reiny,

I understand your explanation.

Thank you
