Question

A dice is thrown once. Find the probability of getting an even number.

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

Answer 1

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

We know that sample space S on throwing a dice is
$S=(1,2,4,5,6)$
$\therefore$ Total number of cases (possible outcomes) n(S) = 6
Event E: getting an even number $=2,4,6$
Number of favourable cases $=n\left(E\right)=3$
Required probability $=P\left(E\right)=\frac{n\left(E\right)}{n\left(S\right)}=\frac{3}{6}=\frac{1}{2}$
