Both wrong.  Where'd you guys get those 1% values, anyway?

1 - 0.001 = 0.999, sure enough.

But 0.999 ^ 100 = 0.904792147...., which means there's about 90% chance of no catastrophe, or about 10% chance of a mess. Strangely, neither of you got the 10% number, even though it's not just correct, it's also what you'd guess if you didn't know anything (1 chance in 1000, repeated 100 times, give about 1 chance in 10 of hitting).


Have you never heard of a typo or clerical error? I make them all the time.

It is nice to see someone actually read that post.
