Determining if events are independent or dependent

Question description

When trying to determine if the events are independent or dependent the formula is the probability of A and B divided by the probability of B but you can also do it as the probability of B and A divided by the probability of A.  Does it matter which way it is done if the problem just asks if they are independent?
