Well, not a statistician either, but the odds are irrelevant. The key
is just as likely to be found at position 1 as it is to be found at
position 100. There is no statistical difference in the probability of
being found at either location. You're right, the odds are in favor of
it being in the first 99 positions but that doesn't perclude the
possibility and potential reality that it is in the last position.
Relax, sit back, and let the computers crucnh the numbers.
