Question

There are $6$ balls of weight $1kg$, $2kg$, $3kg$, $4kg$, $5kg$ and $6kg$ in a bag. Find the probability that the $3$ kg ball is drawn if we draw one ball from the bag.

• A. $\frac{1}{3}$
• B. $\frac{1}{4}$
• C. $\frac{1}{5}$
• D. $\frac{1}{6}$

Answer 1

The correct option is D $\frac{1}{6}$

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

$\therefore$ number of balls drawn $=1$

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

probability of getting 3kg ball $=P\left(A\right)$

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