Question

A dice is thrown once. Find the probability that outcome is even no.

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

Answer 1

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

Given:

Die is thrown once

To find:

The probability that outcome is even number.

Total number of ways = $1,2,3,4,5,6=6$ ways

Out of these ways, even numbers are $2,4,6$

Hence the number of favourable ways = 3

We know,

$P\left(\text{getting a even number}\right)=\frac{\text{No. of favourable ways}}{\text{Total no. of ways}}=\frac{3}{6}=\frac{1}{2}$
