Sorry if I’m goofing up here, but I got confused about the math. You in “How do we look at this in the Factored Set Paradigm,” you say that P(Z=0) = (1%+9%)/(81%+9%) = 1⁄9 = 11.111...%
It seems like P(Z=0) is actually (1%+9%)/(1%+9%+81%+9%) = 10%. Am I misreading something here?
I think you’re correct that P(Z=0) is 1⁄10 -- the author seems to have been calculating the odds ratio instead of the probability. (In fact, they correctly say that P(Z=0) is 1⁄10 later on in the post).

Fixed, thanks!
