Question
Determine whether the events E and F are independent or dependent. Justify your answer. ..... (a) E: A person living at least 70 years. F: The same person regularly handling venomous snakes. A. E and F are dependent because regularly handling venomous snakes can affect the probability of a person living at least 70 years. B. E and F are dependent because living at least 70 years has no effect on the probability of a person regularly handling venomous snakes. O C. E and F are independent because living at least 70 years has no effect on the probability of a person regularly handling venomous snakes. O D. E and F are independent because regularly handling venomous snakes has no effect on the probability of a person living at least 70 years. (b) E: A randomly selected person finding cheese revolting. F: A different randomly selected person finding cheese delicious. A. E cannot affect F and vice versa because the people were randomly selected, so the events are independent. B. E can affect the probability of F, even if the two people are randomly selected, so the events are dependent. O C. E can affect the probability of F because the people were randomly selected, so the events are dependent. D. E cannot affect F because "person 1 finding cheese revolting" could never occur, so the events are neither dependent nor independent. (c) E: The war in a major oil-exporting country. F: The price of gasoline. A. The price of gasoline could affect the war in a major oil-exporting country, so E and F are dependent. O B. The war in a major oil-exporting country could affect the price of gasoline, so E and F are dependent. C. The war in a major oil-exporting country could not affect the price of gasoline, so E and F are independent. O OO
