ASSIGNMENT 01 (SEMESTER 1) Consider the following sets, where U represents a universal set: U = {0/ , a, b, c, {b}, {c}, {b, c}} A = {0/ , {b, c}} B = {a, {b}, {c}} C = {0/, a, b, c}. Questions 1 to 10 are based on the sets defined above. NOTE: The Venn diagrams in study unit 4 will help you to understand the definitions in study unit 3. Question 1 Alternative 1 B = U − B = {0/ , a, b, c, {b}, {c}, {b, c}} − {a, {b}, {c}} = {0/, b, c, {b, c}} Set complement: The elements 0/, b, c and {b, c} belong to U but not to B. Refer to study guide, pp 42, 43. Question 2 Alternative 1 A − C = {0/ , {b, c}} − {0/ , a, b, c} = {{b, c}}. Set difference: Only the element {b,
