Question
100%

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 19.1​% daily failure rate. If the student has two such alarm​ clocks, what is the probability that they both fail on the morning of an important final​ exam?
