現代数学の系譜 工学物理雑談 古典ガロア理論も読む68 - 暇つぶし2ch55:ied in concluding that P(X<=Y)=0, nor that {X<=Y} is measurable (though for each fixed y, {X<=y} is measurable). And indeed it's not measurable: for were it measurable, we could use Fubini to conclude that it has null probability. Note that one can repeat the argument without CH but instead using an extension of Lebesgue measure that assigns null probability to every subset of cardinality <c, so clearly there is no refutation of CH here.
