Q2. 2.8 A component with time to failure T has failure rate function z(t) = kt fort > 0 and k > 0 (a) Determine the probability that the component survives 200 hours, when k = 2.0 . 10-6 (hours) -2. (b) Determine the MTTF of the component when k = 2.0 . 10-6 (hours)-2. (c) Determine the probability that a component which is functioning after 200 hours is still functioning after 400 hours, when k = 2.0 . 10-6 (hours)-2
