Problem 1 1- The failure rate of the milling and grinding machines are 0.0003 and 0.0002 failure/hour, respectively. The probability that any Turning Machine will fail immediately after 50 hours given that it does not fail until 50 hours is 0.0035. Calculate the probability that the system will fail at any point during the 50 hours of work. Note that the failure rate of the machines is constant.
