What is the probability of getting a sum 9 from two throws of a dice?

$\frac { 1 } { 6 }$

$\frac { 1 } { 8 }$

$\frac { 1 } { 9 }$

$\frac { 1 } { 12 }$

Answer : Option C

Explanation :

In two throws of a dice, n(S) = (6 x 6) = 36.

Let E = event of getting a sum ={(3, 6), (4, 5), (5, 4), (6, 3)}.

P(E)= $\frac { n(E) } { n(s)}$ = $\frac { 4 } { 36 }$ = $\frac { 1 } { 9 }$
