Let R be a ring and let M, N, U, V be R-modules such that there existR module homomorphisms α : M N, β : u--w, γ: M-+ U and δ: N V such that the following diagram is commutative: (recall that commutativity of the diagram means that δ ο α γ)...
Problem 1.11. Let P be a probability measure on R, equipped with the Borel ơ-algebra. Let F(x)-P((-00,2]). P rove that f is non-decreasing right-continuous, F(x) → 0 as x →-00, and F(x) → 1 as x → oo. Prove that if P and Q are two probability measures such that P((-oo, x Q((-00,x]) for all x rational, then P , ie. P(A) = Q(A) for any Borel- measurable set A.
