Problem 4.3.8.

In order to guarantee smooth operation, the University has three web- servers. Each can handle the traffic by itself, and the probability that each is not working on a given day is 10%, independently of the other servers. Assuming that the system is up, what is the probability that only one server is functioning?

Manufacture of a certain component requires three different machining operations. Machining time for each operation has a normal distribution, and the three times are independent of one another. The mean values are 15, 20, and 30 min, respectively, and the standard deviations are 2, 1, and 1.7 min, respectively. What is the probability that it takes at most 1 hour of machining time to produce a randomly selected component? (Round your answer to four decimal places.)

A cloud computing provider has 475 customers and a farm of 250 compute servers each having 4 cores. The company statistics indicate that at the peak hour the workload requirements of its customers are such that each requires {0,1,2,3,4} cores with uniform probability. Use the approximation based on Central Limit Theorem to answer the following questions. 1. Compute the outage probability, i.e., the probability that there are not a sufficient number of cores to meet customers demands. 2. The company...

In vitro fertilization (IVF) has become commonplace and fertility clinics in the US can nearly guarantee the child's gender. Gender selection is forbidden in many countries because politicians assume it will be used to produce boy babies. India and China have areas of the country where the gender imbalance is so skewed to men that they will have trouble finding spouses. In the Fertility Institutes of LA Dr. Steinberg asserts that there is roughly a 50/50 balance. What do you...

Problem: A university administrator is interested in whether a new building can be planned and built on campus within a four-year time frame. He considers the process in two phases. Phase I: Phase I involves lobbying the state legislature and governor for permission and funds, issuing bonds to obtain funds, and obtaining all the appropriate legal documents. Past experience indicates that the time required to complete phase I is approximately normally distributed with a mean of 16 months and standard...
