Gordon, I fixed the Z1/Y2 swap.

"Vice versa" seems to have been interpreted ambiguously so I substituted "doesn't mean you're allowed to reason Black(x)->Raven(x)" which was what I meant.

Gordon, the whole business about P(R|B) = 0 makes no sense to me, and I suspect that it makes no sense even in principle. "If we learn that something is black, we know it cannot possibly be a raven"?
