Mathematics: An airline company is considering a new policy of booking as many as 191 persons on an airplane that can seat only 180. (past studies have revealed that only 85% of the booked passengers actually arrive for the flight.) estimate the probability that if the company books 191 persons. not enough seats will be available.

They are not congruent because they are the same shape just flipped around...

1.3559644*10^-^5

Step-by-step explanation:

From the information given we extract the following data

Total Number of Trials (N) = 191

Required Value (x) = 181 (notice it is not 180 since at that value we have enough passengers)

Odds of success (p) = 0.85

Using the binomial formula for calculating probability, i.e.

$P(x; N, p) = nCx * p^x *(1-p)^{N-x}$

Inputting the values

$P(181; 191, 0.85) = 191C181 *0.85^{181} *(1-0.85)^{191-181} \\ P(181; 191, 0.85) = 1.3559644*10^-^5$
