Option C:

**Solution:**

Sample space for two dice

Number of sample space = 36

Pair getting sum of 12 = (6, 6)

Number of pair getting sum of 12 = 1

Pair getting doublet = (1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6)

Number of pair getting doublet = 6

Total number of pair getting sum of 12 or doublet = 1 + 6 = 7

Probability of getting sum of 12 or doublet

**Hence, **** is the probability of getting a sum of 12 or doublet when rolling a pair of dice.**
