i have no idea, all i know is that when we figure it out in the calculator (TI-83+ for me), we are using the nCr and and nPr things. I assume this one will be nCr because order does not matter. I figured that it would be 80 nCr 10 or (C(80,10)) divided or subtracted by something that represnts the C(8,1), i just can't figure it out.
