The exponential distribution has some specific values in statistics. For example, if its rate is A then the expectation is 1/A. A generator generates electricity for a system with energy storage. If the generator fails, the system runs out of energy exactly five days later. Let the time to failure X for the generator be exponentially distributed with expectation value of 600 days while Y denotes the time until the system runs out of energy (five days later). 1. What is the probability P that the generator will fail within the first 600 days? 2. What is the quantile of the random variable Y with this probability? 3. Calculate the coefficients of variation for X and Y.
