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 person insisting on using a fountain pen always./The same person having ink stains on every one of his shirts. Choose the correct answer below. The events are dependent since a person insisting on using a fountain pen always may increase the probability of having ink stains on every one of his shirts. The events are independent since a person insisting on using a fountain pen always has no effect on the probability of having ink stains on every one of his shirts. The events are dependent since a person insisting on using a fountain pen always has no effect on the probability of having ink stains on every one of his shirts. The events are independent since a person having ink stains on every one of his shirts has no effect on the probability of insisting on using a fountain pen always. Randomly selecting a TV viewer who is watching the evening news./Randomly selecting a second TV viewer who is watching the evening news. Choose the correct answer below. The events are independent since randomly selecting a TV viewer who is watching the evening news has no effect on the probability of randomly selecting a second. The two events are technically dependent but can be treated as if they are independent because small samples are drawn from a large population. The events are dependent since randomly selecting a TV viewer who is watching the evening news may decrease the probability of randomly selecting a second. The habit of wearing a wedding ring on the left ring finger./The probability of getting asked out on a date. Choose the correct answer below. The habit of wearing a wedding ring on the left ring finger could affect the probability of getting asked out on a date, so the events are dependent. The habit of wearing a wedding ring on the left ring finger could not affect the probability of getting asked out on a date, so the events are independent. The habit of wearing a wedding ring on the left ring finger could affect the probability of getting asked out on a date, so the events are independent. The probability of getting asked out on a date could affect the habit of wearing a wedding ring on the left ring finger, so the events are dependent.
