An office has 30 computers. Seventeen of the 30 are Macintosh, and the remaining thirteen are windows. Two computers are randomly selected without replacement.
What is the probability of randomly selecting a Macintosh given that the first computer selected was a windows machine? If needed, round to FOUR decimal places.
Pr(Macintosh|Windows) = ___________
Homework Answers
Macintosh = 17
Windows = 13
Total = 30
Selection 1: WINDOWS
P(Selection 1: WINDOWS) = 13/30 = 0.4333
Selection 2: Macintosh
Macintosh = 17
Windows= 12
Total = 29
P(Selection 2: Macintosh) = 17/29 = 0.5862
So,
Answer is:
0.5862

An association surveyed office workers to learn about the anticipated usage of office computers for personal holiday shopping. Assume that the number of hours a worker spends doing holiday shopping on an office computer follows an exponential distribution. The study reported that there is a 0.58 probability that a worker uses an office computer for holiday shopping 5 hours or less. Is the mean time spent using an office computer for holiday shopping closest to 5.8, 6.2, 6.6, or 7.0...
