A subset A, of an ordered set is convex when
for all x,y in A, for all a, (x <= a <= y implies a in A).

I will call an interval an order convex subset of Q.
Given an interval, what's the probablity that it's
open, closed, both, neither?

Given an open subset of Q, what's the probablity that it's clopen?
Given an closed subset of Q, what's the probablity that it's clopen?
