Question

According to a survey published by ComPsych Corporation, 54% of all workers read e-mail while they are talking on the phone. Suppose that 20% 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.

\[1-.2=.8\]

Answer 4

and last one is 80% of the 54% in other words
\[.54\times .8\]

Answer 5

thank you
