1. The problem statement, all variables and given/known data Two dice are rolled. What is the probability that at least one is six? If two faces are different, what is the probability that at least one is six? 2. Relevant equations 3. The attempt at a solution I have no clue. Although the first one shouldn't be that hard, but it's "at least", so I don't really know. 1-P(0), I guess, but I'm not sure how to get P(0).
