Math Problem Statement
Question content area top Part 1 Assume that there is a 6 % rate of disk drive failure in a year. a. If all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. If copies of all your computer data are stored on four
independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive? Question content area bottom Part 1 a. With two hard disk drives, the probability that catastrophe can be avoided is enter your response here . (Round to four decimal places as needed.)
