Please answer Problems 1 and 2 thoroughly. Problem 1: Let X be a set. Define a partial ordering ≤ on P(X) by A ≤ B if and only if A ⊆ B. We stated the following two facts in class. In this exercise you are asked to give a formal proof of each: (a) (1 point) If A, B ∈ P(X), then sup{A, B} exists, and sup{A, B} = A ∪ B. (b) (1 point) If A, B ∈ P(X),...
