Interpretation of Multiplicity Function

  1. Apr 8, 2014 #1
    Hi. I am trying to understand the multiplicity function Ω!/L!(Ω-L)! where Ω= number of boxes and L= number of distinguishable boxes. I just want a simple intuitive explanation. I have seen a couple of these but none of them ever stick. The term that confuses me the most is the (Ω-L)!

    Any help would be greatly appreciated.

    Awesome. I had discovered that the trick is to divide by (n-r)! in order to divide out the rest of the n!, but I guess I had forgotten. Thank you that was a great explanation. It makes complete sense now.
