Question

In a throw of a die, the probability of getting an odd prime number is

• A. $\frac{1}{2}$
• B. $\frac{1}{4}$
• C. $\frac{1}{3}$
• D. $\frac{1}{6}$

Answer 1

The correct option is C $\frac{1}{3}$

Total number of outcomes when a die is rolled = 6
Outcomes having an odd prime number = 3, 5
$\therefore \text{Number of favourable outcomes}=2$
$\therefore \text{P(getting an odd prime number)}=\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$
$=\frac{2}{6}$
$=\frac{1}{3}$

Hence, the correct answer is option (c).
