Systron Donner Inertial manufactures inertial subsystems for automotive, commercial/industrial, and aerospace and defense applications. The sensors use a one-piece, micro machined inertial sensing element to measure angular rotational velocity or linear acceleration. The mean time between failures (MTBF) for a single axis sensor is 400,000 hours. a. Find the probability that a sensor lasts at least 30 years, assuming continuous operation. (Use 365 days per year. Round your answer to 4 decimal places.)
