Question

the principle of redundancy is used when system reliability is improved through redundant or backup components. assume that a students alarm clock has a 18.1% daily failure rate. complete parts (a) through (d) below.
a. what is the probability that the students alarm clock will not work on the morning of an important final exam? (round to three decimal places as needed.)

Explanation:

Step1: Identify the failure - rate

The daily failure rate of the alarm clock is given as 18.1% or 0.181 in decimal form.

Step2: Determine the probability of non - working

The probability that the alarm clock will not work on a given day is equal to its failure rate.
$P(\text{not work}) = 0.181$

Answer:

0.181
