The number of all possible outcomes is

    17 + 35 + 42 + 13 = 107.


The favorable outcomes are 42 green marbles PLUS 3 marbles numbered "2" of other colors.
In all, there are 42 + 3 = 45 favorable outcomes.


All outcomes are of the same likelihood.


Therefore, the answer to the problem's question is

    P = 45%2F107.
