Quizplus · Accepted Answer

In order to determine if two events are independent, we must compare their joint probability to the product of their individual probabilities. In this case, we would need to compare the probability of being male and liking beer to the product of the individual probabilities of being male and liking beer. Without this information, we cannot conclude that the two events are independent.
