Question

5. A ball is drawn randomly from a jar that contains 11 red balls, 5 white balls, and 6 yellow balls. Find the probability of drawing a white ball.

Answer 1

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}`
