The possible outcomes when three dice are rolled are

6 \cdot 6 \cdot 6

Therefore, the number of possible outcomes:

6^{3}

Find the number of favorable outcomes of the sum of the numbers coming up when rolling 3 dice is greater than 16:

4

Probability

= \frac{number of favorable outcomes}{total number of outcomes}

= \frac{4}{6 ^{3}}

\frac{4}{6 ^{3}} = \frac{1}{54}

= \frac{1}{54}
