Draw set symbols for: • NUMBER BASES TERM 1 TOPICS • FINITE SYSTEM e) Equal set d) Null set D = { a, e, I, o, u} c) Write down all members of 4. Study the Venn diagram below and answer the questions that follow. (iii) A and D. 5. Given that X = { 0, 1, 2, 3, 4} and Y = { 1, 3, 6, 9, 12} B = { 5, 6, 7, 8} a) Describe set A 3. Draw a venn diagram and shade the regions below. a) Find n(A – B) b) n(B – A) a) Represent the two sets on the Venn diagram. h) Non equivalent set. C = { 1, 3, 4, 2} and A B e b f a d g c f) Non equivalent set (i) A and C a) Subset of b) Using symbols show the relationship between sets c) Intersection set 2 | P a g e (i) A  B (ii) P  Q (iii) F – G (iv) G – F (ii) B and C i) Set A ii) Set B iii) Set A  B iv) Find n(A  B) b) b) union set g) Equivalent set 2. Give that Set A = { 1, 2, 3, 4} = (AB)’ AB the complement Complement of sets A B Complement of a set means a set of members not in the given set. Draw and shade (AB)’ = (AB)’ 3 | P a g e Note: The symbol for complement of a set Q = {1, 2, 3, 5, 7} P’ = {1, 2, 3} * Find n(PQ) (i) X  Y (ii) n(X  Y) (iii) n (Y – X ) OR WK. 1: Lesson 3 b) From the venn diagram, find Example = (AnB)’ Shading regions for complement of a set and Given that; P = {4, 3, 6, 7, 9} A B Elements in the universal set but
