Answer:

The sum of two dice can range from 2 to 12. To get a sum of 3, the only possible combinations are (1,2) and (2,1), since there is only one way to get each of those sums.

There are a total of 6 x 6 = 36 possible outcomes when two dice are rolled, since each die has 6 possible outcomes.

Therefore, the probability of rolling a sum of 3 is:

P(D1 + D2 = 3) = number of ways to get a sum of 3 / total number of possible outcomes

P(D1 + D2 = 3) = 2 / 36

Simplifying by dividing both the numerator and denominator by 2, we get:

P(D1 + D2 = 3) = 1 / 18

Therefore, the probability of rolling a sum of 3 with two standard dice is 1/18.
