Let Ω = [0, 1], and let F be the collection of every subset of Ω such that the subset or its complement is countable. Let P(·) be a measure on F such that forA∈F,P(A)=0ifAiscountableandP(A)=1ifAc iscountable.
(a) Is F a field? Also, is F a σ-field? (Note that a field is closed under finite union while a σ-field is closed under countable union.)
(b) Is P finitely additive? Also, is P countably additive on F ?
