According to a survey,71

71%of all workers reade-mail while they are talking on the phone. Suppose that25

25%of those who reade-mail while they are talking on the phone write personal "to-do" lists duringmeetings. Assuming that these figures are true for all workers, if a worker israndomly 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 whiletalking on the phone?

(c)The worker does not write personal "to-do" lists and does read e-mail whiletalking on the phone?
