Yep, 7920 is right. For the formula nCr, you plug in 4 for n, and 11 for r. You multiply the first four numbers from 11 to 1 backwards, as if you were doing a regular probability problem. 11 x 10 x 9 x 8 = 7920

I don’t know formulas, but I’d say that there are 11 committee possibilities. (Now that I’ve read some of the other answers, I realize my guess was pretty lame.)

I have no idea what nCr is and can only assume you’re doing this for some sort of homework help (as this is pretty much identical to another “trivia” question you just posted), but I’ll asnwer, anyway.
There are 7,920 committee combinations.
