DETAILS ASWSBE14 6.E.051.MI. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The mean time between fallures (MTBF) is a common metric used to measure the performance of manufacturing systems, MTBF is the elapsed time between failures of a system during normal operations. The failures could be caused by broken machines or computer errors, among other failures. Suppose that the MTBF for a new automated manufacturing system follows an exponential distribution with a mean of 12.4 hours. (a) What is the probability that the automated manufacturing system runs for more than 18 hours without a fallure? (b) What is the probability that the automated manufacturing system runs for 9 or fewer hours before failure? (c) What is the probability that the automated manufacturing system runs for more than 6 hours but less than 11 hours before a failure? Nood Help? Master
