Let Prob be a probability function on the power set P(Ω) of a sample space Ω. Let B be a set such that Prob(B) > 0. For any set A, define G(A|B) = Prob(A ∩ B) Prob(B) . Prove that for fixed B and as as a function of A, G(·|B) is also a probability function, meaning that G(·|B) satisfies the axioms of probability..

Let S be a set and P be a property of the elements of the set, such that each element either has property P or not. For example, maybe S is the set of your classmates, and P is "likes Japanese food." Then if s ∈ S is a classmate, he/she either likes Japanese food (so s has property P) or does not (so s does not have property P). Suppose Pr(s has property P) = p for a uniformly...
