Let Ω be any set and let F be the collection of all subsets of Ω that are either countable or have a countable complement. (Recall that a set is countable if it is either finite or can be placed in one-to-one correspondence with the natural numbers N = {1, 2, . . .}.) (a) Show that F is a σ-algebra. (b) Show that the set function given by μ(E)= 0 if E is countable ; μ(E) = ∞ otherwise...
