Suppose that a grocery store purchases 5 cartons of skim milk at the wholesale price of $1.20 per carton and retails the milk at $1.65 per carton After the expiration date, the unsold milk is removed from the shelf and the grocer receives a credit from the distributor equal to 3/4 of the wholesale price. If the probability distribution of the random variable X, the number of cartons that are sold from this lot is:
| x | 1 | 2 | 3 | 4 | 5 |
| f(x) | 1/15 | 2/15 | 3/15 | 4/15 | 5/15 |
Find the Expected Profit.
