    work the numerator and the denominator separately. So do 9 choose 3, get a number then do 11 choose 3 and get a number. Once you have each part down to a single number you can simplify.

    formula for C \[\huge\rm n.c_r=\frac{ n! }{ r!(n-r)! }\] n.C_r mean n_C_r like stacy suggested do it separately
