Homework Help: Please help with with this combinatorial proof!

  1. Apr 19, 2012 #1
    Say we have sterling numbers of the first kind where we're given s(n, n-2) = 2(nC3) + 3(nC4)
    for n greater than or equal to 4.

    I know the left hand side we have n people, and we wish to seat them at n-2 circular tables, but I need help with the right hand side! I would greatly appreciate any help at ALL!
