(b) A website contains three identical computer servers. Only one is used to operate the site, and the other two are spares that can be activated in case the primary system fails. The probability of a failure in the primary computer from a request for services is 0.005 . Assuming that each request represents an independent trial, what is the mean number of requests until failure of all three spares?

Step 1
The problem involves three identical computer servers, where one is active and the other two are spares. Each server has a probability of failing per service request of 0.005. We need to find the mean number of requests until all three servers fail. Show more…

A Web site is operated by four identical computer servers. Only one is used to operate the site; the others are spares that can be activated in case the active server fails. The probability that a request to the Web site generates a failure in the active server is $0.0001 .$ Assume that each request is an independent trial. What is the mean time until failure of all four computers?
