In a manufacturing process involving several machines, the average down time t (in hours) for a machine that needs repair has the probability density function given below. f(t) = 0.50-0.5t to (a) Find the probability that a failed machine's down time is 3 hours or more. (Round your answer to three decimal places.) (b) Find the probability that a failed machine's down time is 12 hours or more. (Round your answer to four decimal places.)
