Answer:
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.

Inputting the values

1) subtract 2 from both sides:
y-2 = 9x +2 -2
y-2 = 9x
2) divide both sides by 9:
(y-2)/9 = 9x/9
(y-2)/9=x
so it would be (g-10)/f
I believe the answer is 1.343 x 10^5
