c. The next failure occurring between 200,000 and 350,000 hours? (Round your answer to 4 decimal places.) Probability d. What are the mean and standard deviation of the time between failures? Mean hours Standard deviation hoursThe times between failures on a personal computer follow an exponential distribution with a mean of 300,000 hours. What is the probability of: a. A failure in less than 100,000 hours? (Round your answer to 4 decimal places.) Probability b. No failure in the next 500,000 hours? (Round your answer to 4 decimal places.) Probability
