There are 2 ways to roll each of 2-1, 2-3, 2-4, 2-5, 2-6, and only 1 way to roll 2-2.
And since there's 1 way to roll a 2-2, and 11 ways total to roll 2-X: 1 in 11.
If your complaint with this is that I "double-counted" 2-1, 2-3, 2-4, 2-5 and 2-6, then I will agree with you: Yes, I "double-counted" those. I "double-counted" those because I need to cover every situation where "at least one of the dice is a 2" and there are 2 ways to roll each of those.
