A data storage system consists of 3 disk drives sharing a common queue. An average of 53 storage requests arrive per second. The average time to service a request is 0.03 seconds. Assume that arrivals are poisson distributed and that service times are exponentially distributed.
a. What is the probability that a given disk drive is busy?
b. What is the probability that no disk drives are busy?
c. What is the probability that a storage request will have to wait?
d. What is the average number of storage requests present in the system?
