Let F be a family of subsets of a set X such that empty set is the element of F. A subset A of X belongs to F1 if and only if either A is a subset of F or complement of A is the subset of F. A subset B of X belongs to F2 if and only if B is a finite

2. ## Lbesgue measure

Let E(1,2) be the set of all numbers in (0,1) such that their decimal representation does not contain 1 and 2. Prove that E(1,2) is Lebesgue measurable and find the Lebesgue measure of E(1,2).

3. ## math

Let S be the set of all measurable functions on [0,1]. Then the set O of all functions in S equal to 0 a.e on [0,1] makes an additive subgroup of a commutative group S. Show that S/O with the distance p(f,g)=indefinite
