1. Space shuttle astronauts consume an average of 3000 calories per day. One meal normally consists of a main dish, a vegetable dish, and two different desserts. The astronaut can choose from 10 main dishes, 8 vegetable dishes and 13 desserts. How many different meals are possible?
2. A distribution center receives shipments of a product from three different factories in quantities of 60, 30, and 25. Three times a product is selected at random, each time without replacement. Find the probability that (a) all three products came from the third factory and (b) none of the three products came from the third factory. (Round both to the nearest thousandth.)
