Sci Advisor HW Helper P: 2,537 For context I'm looking at: http://www.mtnmath.com/whatrh/node80.html Bell's theorem suggests that a hidden variable λ cannot exist, but, at least the version above makes the assumption that Λ (the set of all posible values of λ ) is a measurable domain s.t. $$\int_{\Lambda} f(\lambda)d\lambda$$ is well-defined. Is there a version of Bell's theorem that does not rely on the ability to integrate the probability function of λ?
