b. A smoker detector system uses two devices. CS200 and WS500. If the smoke is present, the probability
that it will be detected by device CS200 is 0.75; and by device WS500 is 0.84; and if the smoke is
detected by device CS200 the probability that it is detected by device WS500 is 0.92.
Find the probability that
I. The smoke will not be detected by device CS200 given that it has detected by device WS500.
II. The smoke will be undetected
III. The smoke will be detected by at least two devices.
