Let U = {1, 2, 3, 4}, with A = P(U), and let R be the subset relation on A. For each of the following subsets B (of A), determine the lub and glb of B.
(a) B = {{1}, {2}}
(b) B = {{1}, {2}, {3}, {1, 2}}
(c) 5 = {∅, {1}, {2}, {1, 2}}
(d) B = {{1}, {1, 2}, {1, 3}, {1, 2, 3}}
(e) B = {{1}, {2}, {3}, {1, 2}, {1, 3}, {2, 3}}
