I would put in 9 nCr 4 in a calculator. Am I right?

Is it combinations problem? I think it is, so I would put 9 nCr 4.

Yeah, but two committee members must be chosen from faculty and two from students, then you have to start by separating the two groups and working from there.

By the way, if I find out who you are, you get a zero for the project.

Happy Monday!
