Chapter 6, Problem 31CR

To determine

To calculate: the probability on stopping number $4$ .

Answer to Problem 31CR

The probability on stopping number $4$ is $\frac{1}{4}$ .

Explanation of Solution

Given information : thefigure provided in the question,

  

Calculation : to find the probability on stopping on number $4$ , divide the number of favorable outcomes by number of outcomes.

It is shown in the figure that number of favorable outcomes for $4$ = $2$

Number of total outcomes = $8$

  $Probability(onstoppingnumber4)=\frac{numberof\text{ favorable outcomes}}{number\text{ of total outcomes}}$

  $\begin{array}{l}Probability(onstoppingnumber4)=\frac{2}{8}\\ Probability(onstoppingnumber4)=\frac{1}{4}\end{array}$

Hence, The probability on stopping number $4$ is $\frac{1}{4}$ .
