Question

There are $6$ balls of weight $1kg$, $2kg$, $3kg$, $4kg$, $5kg$ and $6kg$ in a bag. Find the probability that the weight of drawn ball is more than 4 kg.

• A. $\frac{1}{3}$
• B. $\frac{1}{2}$
• C. $\frac{1}{4}$
• D. $\frac{1}{6}$

Answer 1

The correct option is A $\frac{1}{3}$

Total possible outcomes $=6$ $i.e.(1kg,2kg,3kg,4kg,5kg,6kg)$

$\therefore$ number of balls having more than 4 kg $=2$

they are $5kg,6kg.$

$P\left(A\right)=\frac{Numberoffavorableoutcomes}{TotalNumberofpossibleoutcomes}$

$\therefore P\left(A\right)=\frac{2}{6}=\frac{1}{3}$
