Answer:

Step-by-step explanation:

x + 3y = 28

Put x = 28 and solve for y:

28 + 3y = 28 <em>subtract 28 from both sides</em>

28 - 28 + 3y = 28 - 28

3y = 0 <em>divide both sides by 3</em>

3y : 3 = 0 : 3

y = 0

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.

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

Inputting the values

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