You roll 2 dice. how likely is it that the 2 numbers will add up to 12 or less?

It is a very high probability. If you role two dice no matter what you will get 12 or less.

It's a 100% chance that the 2 numbers will add up because the highest it can go to is 12, and you said that it's 12 or less, which is all the numbers.
