Exercise 54

An electronic component in a satellite radio has failure rate of ? = 0.000015 units/hour. Find the mean time to failure (MTTF). What is the probability (assuming an exponential probability distribution) that the component will not have failed after 12,000 hours of operation? Calculate your answer using the appropriate mathematical formula and verify your result using Excel.
