. Let A, B and C be subset of a universal set U. (a) Prove that: Ac x Bc ⊂ (A × B)c (the universal set for A × B is U × U). So A compliment x B compliment = AxB Compliment
Recall the following definition: For two sets A and B, the difference set A \ B is the set consisting of those objects that are members of A but not members of B: A \ B = {x ∈ A : x is NOT ∈ B}. Please provide a thorough answer to the following questions. (a) Prove or disprove: For all sets A, B, C, if A \ C = B \ C, then A = B. (b) Prove or...
