QuestionGiven a $6\%$ disk drive failure rate, find the probability of at least one working drive:
a. For 2 drives: 0.9964 b. For 3 drives: (calculate and round to six decimal places)

Studdy Solution
Calculate the probability of at least one hard disk drive not failing.
$$Probability\, of\, at\, least\, one\, not\, failing = -0.000216 =0.999784$$With three hard disk drives, the probability that catastrophe can be avoided is0.999784.
