Question 1006419: What formula do I use to solve for: A restaurant offers a dinner special that lets you choose from 10 entries, 8 side dishes, and 13 desserts. You can choose one entree, one side dish and 2 deserts. How many different meals are possible? I tried 31!/1!*1!*2!= but got a weird number on the calculator. According to my textbook, the answer is supposed to be 6240, but I don't think I'm using the right formula. Could you please help?

Question 1006539: Could you please tell me what I did wrong with this problem?
A horse race has 12 entries. Assuming there are no ties, what is the probability that the three horses owned by one person finish first, second, and third?
What I tried: 12!/(12-3)! = 12*11*10*9!/9!= 1320; P(1-owner of 3 horses place 1st, 2nd & 3rd) = 1/1320 = .00076
The textbook says the answer is .005.
Thank you.
