Combinations -

  1. May 8, 2005 #1
    Is it fair to say combinations are just an application of the counting principle? I already understand that permutations are just an application of fundamental principle and that combinations are just an application of permutations. If it's fair to say that combinations are in fact, just an application of the counting principle, then would their be a specific formula that proves as such?

    the combination formula is : C(n,p) = (n!)/(p!)(n-p!) with n>p

    is that what you have meant? :S

    If A is completely contained in B, and B is completely contained in C, then A is completely contained in C.
