Chapter 13, Problem 14PT

To determine

Find the probability for which the pointer lands on purple as shown in figure below.

  

Answer to Problem 14PT

The probability of pointer landing on purple is $\frac{7}{72}$ .

Explanation of Solution

Given information: The given figure is shown as,

  

Calculation: From the geometric probability concept, the probability $P\left(\text{pointer land on purple}\right)$ is evaluated as,

  $\begin{array}{c}P\left(\text{pointer land on purple}\right)=\frac{35°}{360°}\\ =\frac{7}{72}\end{array}$

Hence the probability of pointer landing on purple is $\frac{7}{72}$ .
