Question

An unbiased die is thrown once. The probability of getting an even number is

• A. $\frac{1}{6}$
• B. $\frac{1}{3}$
• C. $\frac{2}{5}$
• D. $\frac{1}{2}$

Answer 1

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

As an unbiased die is thrown once, so the sample space will be:

$S=\{1,2,3,4,5,6\}$

The even numbers are $\{2,4,6\}=A$ (say)

$\therefore$ The probability of getting an even number is

$=\frac{\text{The total no of favorable cases}}{\text{Total no.of possible outcomes}}$

$=\frac{3}{6}=\frac{1}{2}$

Option (d) is the correct answer.
