解答ステップ

The possible outcomes when two dice are rolled are

6 \cdot 6

Therefore, the number of possible outcomes:

6^{2}

Find the number of favorable outcomes of rolling sum of 4 with these dice:

3

Probability

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

= \frac{3}{6 ^{2}}

\frac{3}{6 ^{2}} = \frac{1}{12}

= \frac{1}{12}
