Question 544179: There are twenty women and fifteen men at a party. In how many distinct ways can you form ten couples consisting of one man and one woman?
***
I thought it would be 15C10 * 20C10 * 10! - you choose the men and the women; then the first woman has ten choices, the second has nine, etc. However, I'm not sure what really distinguishes this from a basic Fundamental Counting Theorem problem once you have chosen the men and women; under that interpretation, the 10! is unnecessary.
Thank you!
