Homework Help: Statistics

Posted by Esther on Sunday, April 8, 2012 at 11:04pm.

You are responsible for quickly fixing your company¡¯s computer system when it crashes. You know that there are three possible sources of errors in the system: the disk drive, the memory and the operating system.

From an analysis of historical data, you find that 50% of the errors are disk errors, 30% are memory errors and the remaining errors are operating system errors.

From component performance standards, you know that when a disk error occurs, the probability that the computer crashes is 60%, when a memory error occurs, the probability that the computer crashes is 70%, and when an operating system error occurs, the probability that the computer crashes is 40%.

The company computer has just crashed! You need to quickly decide which component (disk drive, memory or operating system) is the best component to look at first in your attempt to get the computer back on line.

Which component should you investigate first? Support your decision with a detailed calculation of all of the relevant conditional probabilities.
