In a city, 20% of the people drive cadillacs and 29% of business executives drive cadillacs. Are the events "person drives a cadillac" and "person is an executive" independent
Yes, the events "person drives a Cadillac" and "person is an executive" are indeed independent. This is because not all business executives drive Cadillacs (only 29% do), and not all people who drive Cadillacs are business executives.
