Question

In throwing of a fair die, find the probability of turning up of an odd number $\ge 4.$

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

Answer 1

Answer: (C)

$\frac{1}{6}$

$S=\{1,2,3,4,5,6\}$
Let $E$ be the event 'turning up of an odd number $\ge 4$
then $E=\left\{5\right\}$
$\therefore$ $P\left(E\right)=\frac{n\left(E\right)}{n\left(S\right)}=\frac{1}{6}.$
