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.
(a) Suppose K is a compact subset of a metric space (X, d) and x є X but x K Show that there exist disjoint, open subsets of Gi and G2 of (X, d) such that r E Gi and KG2. (Hint: Use the version of compactness we called "having a compact topology." You will also need the Hausdorff property.) b) Now suppose that Ki and K2 are two compact, disjoint subsets of a metric space (X, d). Use (a)...
