    There are eight possible combinations:

    79 79 35
    79 79 37
    79 81 35
    79 81 37
    81 79 35
    81 79 37
    81 81 35
    81 81 37

    Work out the chances of each one and compile into a spectrum.

    There are only 6 possible molecules.

    81 79 is the same as 79 81, as in its the same combination but with double the probability (as I'm sure you know)

    Yes and m/z or m/e whichever is preferred, I'd go with some random (large-ish) number, n, and go up to n+5.
