Most likely they will not tell you the answer, because that will violate the agreement of Dec 1. Schools cannot inform you through any form about your status. Of course you are talking about what they think of your chance here, but that question can be interpreted as "am I accepted?". So the adcom would not tell you a straight answer. If they are nice enough, they will tell you that you have to wait for Dec 1. I agree that you should not ask this question, because you put the interviewers on spot, which is not a good idea.
