Balls in jar is:

white balls is 5.

Red balls is 11.

Yellow balls is 6.


\text{probability}=\frac{Number\text{ of favourable outcome}}{\text{total number of outcome}}

For drawing a white ball then favourable outcome is 5.

The total number of outcome is:


\begin{gathered} \text{total outcome = 11+5+6} \\ =22 \end{gathered}

Then white ball probability is:


\begin{gathered} \text{Probability}=\frac{Number\text{ of favourable outcome}}{\text{total number of outcome}} \\ =(5)/(22) \end{gathered}
