(Round to 3 decimal places.) (g) If a. person does not subscribe to phone service, what is the probability that he/she will subscribe to Internet service? (Bound to three decimal places). (h) Of those individuals who do not subscribe to Internet. service, what proportion will (also) not subscribe to phone service? (i) Of those individuals who subscribe to at least one of the two services, what proportion subscribe to both serviws? (j) Using the Complement Principle (within conditional probability) that we dis- cussed in Lecture #3 (comment 2 on page 7) and... i. your answer to part (f) above, PIIfllB) = ii. your answer to part (3) above, P(B|A) = iii. your answer to part (11) above, P(A|B) =
