Answer:
The required probability is 0.0281
Step-by-step explanation:
Consider the provided information.
Air-USA has a policy of booking as many as 18 persons on an airplane that can seat only 17.
Studies have revealed that only 82% of the booked passengers actually arrive for the flight.
Therefore, the probability of a person arrive is 0.82
Find the probability that t if Air-USA books 18 persons, not enough seats will be available.
Probability that 18 persons arrive = 
Hence, the required probability is 0.0281
Mean is 6 because once you add up all the numbers it will be 60, and dividing that number by how many you have will give you 6
Median is 5 because once you place the numbers in order, 0, 0, 1, 2, 3, 7, 9, 10, 13, 15 the middle number in the set is between 3 and 7 and once you find the mean of the two you get 5
