A small ferry runs every half hour from one side of a large river to the other.

Question:

A small ferry runs every half hour from one side of a large river to the other. The number of cars X on a randomly chosen ferry trip has the probability distribution shown here with mean μX=3.87 and standard deviation σX = 1.29.

0.45 - 0.40 0.35 - 0.30 - 0.25 0.20 0.15 0.10 - 0.05 0.00 1 2 3 4 5 X = Number of cars Probability

The cost for the ferry trip is $5. Define M = money collected on a randomly selected ferry trip.

a. What shape does the probability distribution of M have?

b. Find the mean of M.
