I don't think so. YOu're thinking of an experiment that would go like this -- a very large urn has a million balls in it, all but one white. If you draw all the balls, obviously one of them will be white. But if you draw and replace, then in each draw your chances of coming up white are still one in a million. So your premise depends on the trials being dependent on each other. Each null result increases the likelihood of a non-null result subsequently. So it depends on exactly what we're talking about, which I have forgotten.

Yes. This is tricky, but probability, as I understand it, is not really a matter of prediction. So what we are talking about is a situation not before the millionth & one roll of the dice but _after_ all 1 million and one rolls have occurred, and we know the results of NONE of the rolls. What is the probability that when we open the record books to check on what has happened that someplace in that record a roll of five has occurred.
