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.
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?
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
Hello Reiny,
I understand your explanation.
Thank you
Yes, your answers are correct.
To find the number of seats expected to be empty, you can calculate 6% of the total number of seats available. In this case, 6% of 300, which is (6/100) * 300 = 18. So, 18 seats are expected to be empty.
If the airline overbooked the flight by 10 passengers, then you can add 10 to the total number of seats and calculate the percentage of passengers showing up. So, by adding 10 to 300, you get 310. The probability that a passenger will show up is still 94% (100% - 6% = 94%), so (94/100) * 310 = approximately 291 passengers are expected to show up.
Therefore, you are correct that 18 seats are expected to be empty and approximately 291 passengers are expected to show up for the flight.
