The principle of redundancy is used when system reliability is impeoved through redundant or backup components. Assume that a stident's alarm clock has a 7.7 k daly falure rate. Camplote parts (a) through (d) below: a. What is the probability that the student's alarm clock will not work on the moring of an important final exam? (Round to three decimal places as needed.) b. If the student has two such alarm clocks, wtat is the probabilify that they both fal on the moming of an important final exam? (Round to five decimal places as needod) c. What is the probability of not being awakened if the student uses three independent alarm clocks? (Round to five decimal places as needed)
