    Probability (2)

    Monitoring quality of power equipment. Mechanical Engineering (Feb. 2005) reported on the need for wireless networks to monitor the quality of industrial equipment. For example, consider Eaton Corp., a company that develops dis- tribution products. Eaton estimates that 90% of the electrical switching devices it sells can monitor the quality of the power running through the device. Eaton further estimates that of the buyers of electrical switching devices capable of monitor- ing quality, 90% do not wire the equipment up for that pur- pose. Use this information to estimate the probability that an Eaton electrical switching device is capable of monitoring
    power quality and is wired up for that purpose.
