Question

The principle of redundancy is used when system reliability is improved through redundant or backup components. Assume that a​ student's alarm clock has a 15.3​% daily failure rate. Complete parts​ (a) through​ (d) below. a. What is the probability that the​ student's alarm clock will not work on the morning of an important final​ exam?

Answer 1

`Pr = 0.153`

Explanation:

Given

`p = 15.3\%`

Required

Probability of alarm not working

`p = 15.3\%` implies that the alarm has a probability of not working on a given day.

So, the probability that the alarm will not work on an exam date is:

`Pr = 15.3\%`

Express as decimal

`Pr = 0.153`
