Transitive Property of Subsets: For all sets A, B, and C if A ⊆ B and B ⊆ C, then A ⊆ C Procedural Versions of Set Definitions Let X and Y be subsets of a universal set U and … WebS A 2 A 1 A 3 B 10 15 20 4 We see that in fact the sets B ∩A1, B ∩A2, and B ∩A3 form a partition of B. Therefore B = B ∩A1 + B∩A2 + B∩A3 = 10 + 20 + 15 = 45 7. Determine whether each of the following sets is countable or uncountable. (a) A= {1,2,· · ·,1010}. (b) B = {a+ b√2 a, b ∈ Q}. (c) C = {(X, Y) ∈ R2 x2 + y2 ≤ 1}.
