Question

When a dice is thrown, what is the probability of getting an even number?

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

Answer 1

The correct option is B

$\frac{1}{2}$

Sample space for a dice thrown once = S {1,2,3,4,5,6}

$\Rightarrow$Total number of outcomes = $6^1=6$

Number of favourable outcomes (getting an even number) = 3

The favourable outcomes are 2,4,6.

Probability of an event, P(E) =$\frac{\text{number of favourable outcomes}}{\text{total number of outcomes}}$

Probability of getting an even number, P(E) = $\frac{3}{6}$=$\frac{1}{2}$
