When rolling two number cubes what is the probability of rolling at least one six?

When rolling two number cubes (standard six-sided dice), the probability of not rolling a six on a single die is 5/6. Therefore, the probability of not rolling a six on both dice is (5/6) × (5/6) = 25/36. To find the probability of rolling at least one six, we subtract this result from 1: 1 - 25/36 = 11/36. Thus, the probability of rolling at least one six when rolling two dice is 11/36.
