What is the probability of getting a 10 or a 11 when a pair of dice are rolled?

Since we're looking for 10 OR 11, it means we just need to add the probabilities of finding each separately. So what are the odds of finding a 10? And then what about 11?

Depending on how you've been taught so far to do probabilities, one way would be to use a tree diagram.
