Well, I will admit that I don't know the answer. I'm not very good with probability. However, I do know that the SECOND one is wrong. Why? Because you multiply by 0. And what happens when you multiply by 0? You get zero. And what can you NOT do with 0? Divide. Thus your second answer is not correct.
