I need help on 5-8, please.

S. Suppose that 40 percent of the subscribers to a cable television service watch the shopping channel at least once a week, You are to design a simulation to estimate the probability that none of five randomly selected subscribers watches the shopping channel at least once a week. Which of the following assignments of the digits 0 through 9 would be appropriate for modeling an individual subscriber's behavior in this simulation? (n) Assign "0, 1, 2, 3, 4" as watching the shopping channel at least once a week and "5, 6, 7, 8, and 9" as not watching. (b) Assign "0, 1, 2, 3" as watching the shopping channel at least once a week and "4, 5, 6, 7, 8, and 9" as not watching. (c) Assign "1, 2, 3, 4, 5" as watching the shopping channel at least once a week and "6, 7, 8, 9, and 0" as not watching. (d) Assign "0" as watching the shopping channel at least once a week and "1, 2, 3, 4, and 5" as not watching; ignore digits "6, 7, 8, and 9." (e) Assign "4" as watching the shopping channel at least once a week and "0, 1, 2, 3, 5, 6, 7, 8, and 9" as not watching. 6. Toby is planning to fly from Cincinnati to Las Vegas and will take the Airtight Airlines flight that leaves at 9 A.M. The Web site she used to make her reservation states that the probability that the flight will arrive in Las Vegas on time is 0.75. Of the following, which is the most reasonable explanation for how that probability could have been estimated? (A) By using an extended weather forecast for the date of her flight, which showed a 25% chance of bad weather (B) By making assumptions about how airplanes work, and factoring all of those assumptions into an equation to arrive at the probability (C) From the fact that, of all airline flights arriving in Nevada, 75% arrive on time (D) From the fact that, of all airline flights in the United States, 75% arrive on time (E) From the fact that, on all previous days this particular flight had been scheduled, it had arrived on time 75% of those days 7. If P(A) = 0.32 and P(B) = 0.61 and A and B are independent, what is P(A or B)? (a) 0.7348 (b) 0.1952 (c) 0.6352 (d) 0.93 (e) The answer cannot be determined from the information given. 8. Which of the following statements is true for two events, each with probability greater than 0? A) If the events are mutually exclusive, they must be independent. B) If the events are independent, they must be mutually exclusive. C) If the events are not mutually exclusive, they must be independent. D) If the events are not independent, they must be mutually exclusive. 3) If the events are mutually exclusive, they cannot be independent
