A shipment of forty cases of canned food was received at a food warehouse. The shipping document shows that there are 4 cases of canned tomatoes, 6 cases of canned milk, 12 cases of canned beans, and 18 cases of canned soup. However, the company that put the cans into the cases forgot to put a label on the outside of each case that showed what type of canned food was inside each case. Therefore, the type of food inside each case will have to be identified by the company receiving the shipment.

Part C: If one case is selected at random from the shipment of 40 cases, and then another case is immediately selected from the remaining cases, what is the chance that both cases will contain canned milk? Show the equation you used, the numbers you used in that equation, and exactly how you arrived at your final answer expressed as a percentage.
