What is the probability that you don't roll a sum of 3 when you roll two fair dice?

I think of it this way. Take it as two unique 6-sided dice, then you have 36 possible outcomes (6 times 6). Two of these outcomes will add to equal 3 (2 & 1, and 1 & 2), so there are 34 [36-2] outcomes which don't sum to 3. The probability is 34/36 or about 94.44 percent chance.
If you're asking what the probability you don't roll AT LEAST three is, the only roll on two normal dice less than three is two, and there's only one way to roll it: 1,1. So the probability of not getting AT LEAST three on two fair dice is 1/36.

It is 1/3.

It is 1: if you roll the die often enough. On a single roll of a fair die, the probability is 1/6.

It is 6/36 = 1/6.
What is the probability of not rolling a sum of 2 with two fair dice?
If you roll them often enough then the probability is 0. For just one roll, the probability is 35/36.
