ExplanationFirst, figure out how many different results that Damon can get: Each die has 6 sides, so the total number of possible outcomes is 6 × 6 × 6 = 216.

Now count out how many of those outcomes total more than 16. There are 3 ways to roll a 17—5, 6, and 6, 6, 5, and 6, and 6, 6, and 5—and 1 way to roll an 18—three 6’s. The probability is thus \(\frac{4}{216}\), which reduces to \(\frac{1}{54}\).
