Question

Probability of getting a sum of $9$ on two throws of a die is

• A. $\frac{1}{9}$
• B. $\frac{1}{6}$
• C. $\frac{1}{8}$
• D. $\frac{1}{10}$

Answer 1

The correct option is A $\frac{1}{9}$

Sum of the outcome will be $9$ in the cases $\left\{\right(4,5),(3,6),(5,4),(6,3\left)\right\}$
$\therefore$ The probability $=\frac{1}{9}$
