    combination


    From where, I can find the proof of the following theorem. I have to to cite it, in my research article.
    Theorem: The combination "N C P-1" is the number of possibilities for P1,P2,P3,...,Pr∈ℤ⁺ such that P1+P2+P3+...+Pr=N+1.

    Re: combination

    Hey makenqau1.

    When you say possibilities can you give an example? Do you have N things and each thing is one of (P1,P2,...,Pr)?
