- Sorry, that should've been

- P = 1 - .9^N
-

- and that, of course, should've been
-
- N = log(1-P)/log(.9)

- The conclusion that I can get any probability I want by choosing the right time
- frame still holds, though.

- It's rather telling that Victor-the-idiot Yackadamn chose to flame me over my
- presumption that GreenHype held true to form and failed to include essential
- information in their propaganda release (as they've done many times in the
- past; for example, the release posted by Jym a couple of months ago that made
- a big thing about the fact that plutonium had been detected on the beaches near
- Sellafield, but neglected to say anything at all about concentrations).
