How about conditional probabilities? If E1 is a proper subset of E2, and both E1 and E2 are measuarable and have probability zero, it is possible that the conditional probability P(E1 | E2) is strictly less than one.
So in some sense we may say that E1 is "less probable" than E2. Btw, I have deleted the groups "sci.physics" and "sci.math" for "newsgroups" and "followup to".
