    Probability problem using a constant

    Hello! I'm taking a probability course this summer and am having a lot of trouble with this problem:

    You have:
    g(x,y) = {g^(x+y-1) boundary: |x-y| <= 1}
    and {0 boundary: |x-y| > 1}
    where g is a constant.
    Find P[ M+N < 3 ].

    I understand how to set up the boundaries, but I'm confused as to how to interpret g as a constant. If anyone can help, it would be greatly appreciated! Thanks!

    1 g is the name of the function, you shouldn't use it as a constant

    2 Is M,N really X and Y??? Where did they come from?

    The total probability is one, so that's how you will compute the constant.
