You have a device that uses a single battery, and you operate this device continuously, never turning it off. Whenever a battery fails, you replace it with a brand new one immediately. Suppose the lifetime of a typical battery has an exponential distribution with mean 205 minutes. Suppose you operate the device continuously for three days, making battery changes when necessary. Find the probability that you will observe at least 25 failures.
Answer to relevant QuestionsIn the previous problem, we ran the experiment for a certain number of days and then asked about the number of failures. In this problem, we take a different point of view.
