We all know that if the ball is 1% in, it is in. What if you think that there is more of a chance that it was out than it was in, and it is not 51-49, but say 95-5? Obviously, you did not see the ball good enough to be 100% sure one way or the other. What should be your call? If a surgeon thinks 95 to 5 that a tumor should be removed at once, should he not do it?
