Extracted text: In a large corporate computer network, user log-ons to the system can be modeled as a Poisson process with a mean of 25 log-ons per hour. • What is the probability that there are no log-ons in an interval of 6 minutes? • What is the median time between log-ons? Hint: This is the interval of time such that the probability of no log-ons during that interval is 0.5.
