Balls in jar is:
white balls is 5.
Red balls is 11.
Yellow balls is 6.
[tex]\text{probability}=\frac{Number\text{ of favourable outcome}}{\text{total number of outcome}}[/tex]For drawing a white ball then favourable outcome is 5.
The total number of outcome is:
[tex]\begin{gathered} \text{total outcome = 11+5+6} \\ =22 \end{gathered}[/tex]Then white ball probability is:
[tex]\begin{gathered} \text{Probability}=\frac{Number\text{ of favourable outcome}}{\text{total number of outcome}} \\ =\frac{5}{22} \end{gathered}[/tex]
