Question

For each given pair of events, classify the two events as independent or dependent. (If two events are technically dependent but can be treated as if they are independent, consider them to be independent.) a. A person missing his debit card./The same person finding that his bank account is empty. Choose the correct answer below A. The events are independent since a person finding that his bank account is empty has no effect on the probability of missing his debit card B. The events are dependent since a person missing his debit card has no effect on the probability of finding that his bank account is empty C. The events are dependent since a person missing his debit card may increase the probability of finding that his bank account is empty. D. The events are independent since a person missing his debit card has no effect on the probability of finding that his bank account is empty. b. Randomly selecting a dime made before 1998./Randomly selecting a second dime made before 1998. Choose the correct answer below. A. The events are independent since randomly selecting a dime made before 1998 has no effect on the probability of randomly selecting a second. B. The events are dependent since randomly selecting a dime made before 1998 may decrease the probability of randomly selecting a second. C. The two events are technically dependent but can be treated as if they are independent because small samples are drawn from a large population c. The habit of eating from the mega-sized fast food menu. The probability of becoming obese. Choose the correct answer below. A. The habit of eating from the mega-sized fast food menu could affect the probability of becoming obese, so the events are dependent.
