According to a survey, 57% of all workers read e-mail while they are talking on the phone. Suppose that 22% of those who read e-mail while they are talking on the phone write personal “to-do” lists during meetings. Assuming that these figures are true for all workers, if a worker is randomly selected, determine the following probabilities (a) The worker reads e-mail while talking on the phone and writes personal “to-do” lists during meetings? (b) The worker does not write personal “to-do” lists given that he reads e-mail while talking on the phone? (c) The worker does not write personal “to-do” lists and does read e-mail while talking on the phone?
