Answer:

B. $1750

Step-by-step explanation:

The mean of the discrete uniform distribution is given by:

$M = \frac{a+b}{2}$

In this problem, we have that $a = 3, b = 11$ .

The expected time to find the car is:

$M = \frac{3+11}{2} = 7$

7 hours are expected to find the car.

The helicopter costs $250 per hour to rent.

7*$250 = $1750

So the correct answer is:

B. $1750
