Chapter 8.5, Problem 28E

To determine

To find the probability that a clock stopped between 3:00 and 6:00.

Answer to Problem 28E

Probability is $\frac{1}{4}$

Explanation of Solution

Given information: The clock stopped between 3:00 and 6:00.

Calculation :

In a interval of 12-hour, every hour clock contains $\frac{1}{12}$ of the time.

The probability that a clock stopped between 3:00 and 6:00 is $\frac{3}{12}=\frac{1}{4}$

Hence, the probability that a clock stopped between 1:00 and 5:00 is $\frac{1}{4}$
