Best ResponseYou've already chosen the best response.0This is probably the 10th question on this subject you've asked about, and it doesn't seem like you're any closer to learning what you need to know to solve these on your own.. Maybe you should actually spend some time reading the book? \[\frac{{10 \choose 2} * {10 \choose 5}}{20 \choose 7}\]
