Answer 1

Find the power set A = {1, {1}} The Power is {phi, {1}, {{1}}, {1, {1}} Let A and B be two sets Let A and B be two sets A Intersection B^bar = {a, b, c} Here B^bar = U - B U = Universal set B Intersection A^bar = {l, c} A Union B = {a, b, c, d, e} By Venn diagram Therefore Venn's diagram, we get A Intersection B = (A Union B) - ((A Intersection B^bar) Union (B Intersection A^bar)) = {a, b, c, d, e} - ({a, b, c} Union {d, e}) implies A Intersection B^bar = {a, b, c, d, e} - {a, b, c, d, e} implies B Intersection A^bar = phi Therefore The Venn's Diagram Will be A Intersection B = phi Let A_n = [-1/n, infinity) n elementof N n = 1, 2, 3... A_1 = [-1, infinity) A_2 = [-1/2, infinity) A_3 = [-1/3, infinity) U^infinity_n = 1 A_n \r\n
