Determine whether the events E and F are independent or dependent. Justify your answer. (a) E: A person going into debt. F: The same person having a credit card. O A. E and F are dependent because having a credit card can affect the probability of a person going into debt. O B. E and F are independent because going into debt has no effect on the probability of a person having a credit card. O C. E and F are independent because having a credit card has no effect on the probability of a person going into debt. O D. E and F are dependent because going into debt has no effect on the probability of a person having a credit card. (b) E: A randomly selected person finding cheese revolting. F: A different randomly selected person finding cheese delicious. O A. E can affect the probability of F, even if the two people are randomly selected, so the events are dependent. O B. E cannot affect F and vice versa because the people were randomly selected, so the events are independent. O C. E cannot affect F because "person 1 finding cheese revolting" could never occur, so the events are neither dependent nor independent. O D. E can affect the probability of F because the people were randomly selected, so the events are dependent. (c) E: The unusually foggy weather in London on May 8. F: The number of car accidents in London on May 8. O A. The unusually foggy weather in London on May 8 could affect the number of car accidents in London on May 8, so E and F are dependent. O B. The unusually foggy weather in London on May 8 could not affect the number of car accidents in London on May 8, so E and F are independent. O c. The number of car accidents in London on May 8 could affect the unusually foggy weather in London on May 8, so E and F are dependent.
