Before you comment , read this:

Some alert readers pointed out that the original version of the comic was off on the math. The narrator in panel 2 said “Now let’s remove all the folks you’ll never meet.” which does indeed conflict with panel 4. I had rewritten these panels to death and my notebook was a garbled mess of alternate lines of dialogue, which made it easy for that erroneous piece of text to slip right in.

I have since gone back and replaced the narration with something that mathematically makes a bit more sense. So don’t be confused when you scroll down and see the earlier comments questioning the logic of this particular comic.

Thanks again to all the alert readers out there!
