OK, letís talk about a real world computer then, a computer with a very
large but finite amount of memory, letís call it X. What is the
probability, even approximately, that the machine will stop before it
reaches X, its memory limit? What is the shortcut algorithm to figure
this out other than running the original program and waiting to see what
happens?

If thatís too hard try this one, how can I calculate if this atom of
tritium I hold in my hand will decay in the next 12.3 years? I donít
demand an exact answer, just show me how to get a probability that is
even a little bit better than what Iíd get by flipping a coin.
