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 a sum of 2 with these dice:

1

Probability

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

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

6^{2} = 36

= \frac{1}{36}
