Question
#8. The computing system at a large university has been forced to shut down 73% of the time when it eperences hardware problems, 12% of the time when it experiences software problems, and 8% of the time when it experiences power problems. Maintenance engineers have determined that the probabilities of hardware, software, and power problems are .01,.05, and.02 respectively (a) What is the probability of the system experiencing a power problem and being forced to shut down? b) What is the probability of the system being shut down? (c) What is the probability that if the sysem has shut down, it was due to a power failure.?Explanation / Answer
