Re: probabilities & measures & computable universes

Are probabilities always and necessarily positive-definite?

I'm asking this because there is a thread, started by Dirac
and Feynman, saying the only difference between the classical
and quantum cases is that in the former we assume the probabilities
are positive-definite.

Thus, speaking of MWI, we could also ask: what is the joint
probability of finding ourselves in a universe alpha and of
finding ourselves in a universe beta, which is 180 degrees
out of phase with the first one (whatever that could mean)?
