27. Regular measures. Consider the probability space (R, B(Rk), P). A Borelset A is regular ifP(A) = inf(P(G) : G Ɔ A, G open,}andP(A) = sup(P(F) : FCA, F closed.)P is regular if all Borel sets are regular. Define C to be the collection ofregular sets.(a) Show Rk E C, ØE C.(b) Show C is closed under complements and countable unions.(c) Let F(R) be the closed subsets of Rk. ShowF(R*) CC.(d) Show B(R) C C; that is, show regularity.(e) For any Borel set AP(A) = sup{P(K): K CA, K compact.)
