Exercise 1.2.3. Decide which of the following represent true statements about the nature of sets. For any that are false, provide a specific example where the statement in question does not hold. (a) If A₁ 2 A2 2 A3 2 A4 are all sets containing an infinite number of elements, then the intersection 1 An is infinite as well. are all finite, nonempty sets of real numbers, 1 An is finite and nonempty. (b) If A₁ 2 A₂ 2 A3 2 A4 then the intersection (c) An (BUC) = (ANB) UC.
