A personal computer is used for ofce work at home, research, communication, personal nances, education, entertainment, social networking, and a myriad of other things. Suppose that the average number of hours a household personal computer is used for education is four hours per day. Assume the times for education are normally distributed and the standard deviation for the times is an hour. Find the probability, rounded to four decimal digits, that a household personal computer is used for education more than 5 hours. Below is a sketch of the normal curve showing the area to be determined
