What is the probability of getting a sum 9 from two throws of a dice ?
A. $$\frac{{1}}{{6}}$$
B. $$\frac{{1}}{{8}}$$
C. $$\frac{{1}}{{9}}$$
D. $$\frac{{1}}{{12}}$$
Answer: Option C
Solution(By Examveda Team)
In two throws of dice, n(S) = (6 × 6) = 36Let E = event of getting a sum 9 = [(3, 6), (4, 5), (5, 4), (6, 3)]
$$\therefore P(E) = \frac{{n(E)}}{{n(S)}} = \frac{4}{{36}} = \frac{1}{9}$$
