Question

A dice is thrown once. Find the probability of getting a prime number.

• A. $\frac{1}{2}$
• B. $\frac{1}{4}$
• C. $\frac{1}{3}$
• D. $\frac{1}{5}$

Answer 1

The correct option is A $\frac{1}{2}$

Sample space S ={1, 2, 3, 4, 5, 6}
Total number of events = 6
a prime number = {2, 3, 5}
$\therefore$ P(a prime number) $=\frac{3}{6}=\frac{1}{2}$
