If two 6-sided number cubes are rolled, what is the probability that a 2 is rolled on the first cube and a 5 is rolled on the second cube?

The probability would be 1/6. Since there is 6 sides on each number cube, for each cube there would only be a 1/6 chance of it landing on a 2 on one cube and a 5 on the other if each cube is rolled once.
