A dice is rolled twice. What is the probability of getting sum 9?

A. $$\frac{{2}}{{3}}$$

B. $$\frac{{1}}{{3}}$$

C. $$\frac{{1}}{{9}}$$

D. $$\frac{{3}}{{9}}$$

Answer: Option C

Solution (By Examveda Team)

Possible event = 6 × 6 = 36
Favourable outcomes = {(3, 6), {4, 5}, {5, 4}, (6, 3)}
∴ Probability
$$\eqalign{ & = \frac{{{\text{Favourable}}}}{{{\text{total}}}} \cr & = \frac{4}{{36}} \cr & = \frac{1}{9} \cr} $$
