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 insisting on using a fountain pen always./The same person having ink stains on every one of his shirts. Choose the correct answer below. A. 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. B. 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. C. 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. D. 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 shirt. b. Randomly selecting a baseball player over the age of 30./Randomly selecting a second baseball player over the age of 30. Choose the correct answer below. A. The events are dependent since randomly selecting a baseball player over the age of 30 may decrease the probability of randomly selecting a second. B. 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 events are independent since randomly selecting a baseball player over the age of 30 has no effect on the probability of randomly selecting a second.

Explanation / Answer

Answer 1 - D. they are independent because When two events are said to be independent of each other, what this means is that theprobability that one event occurs in no way affects the probability of the other eventoccurring.

Answer 2 - A because Two events are dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probabilityis changed.
