    Its the same as considering 1-\mathbb{P}(\text{rolling 4 fives}). Since each die result is independent of the others, what do you think is the value of \mathbb{P}(\text{rolling 4 fives})?

    You are asked to find the probability of the dice showing at most three 5's. Have you considered finding the probability of the dice showing one 5, two 5's, and three 5's?

    Have you done some initial investigation? What were your results?
