  1. We will chake the answer

  2. 5.Which the following given that U is a natural Number , draw a Venn diagrams Page… 13 1) A={1,2,3,4,5,6,7,8,9,10} B={1,3,5,7,9} A N B 2 1 1 4 10 3 3 5 5 9 9 7 7 6 OK 8

  3. Page… 13 2) A={1,2,3,4,5,6,7,8,9,10} B={1,3,5,7,9} C={1,3,5} N A 2 B C 9 9 1 1 1 4 3 3 10 3 5 5 5 7 7 6 8 OK

  4. Page… 13 3)A={1,2,3,4,5,6,7,8,9,10} B={1,3,5,} C={2,4,6} A 7 9 B C 1 1 2 2 3 3 4 4 5 5 6 6 10 8 OK

  5. Union and Intersection VDO –V4 - Union Board VCO – V5 intersection Board แผนภาพ Authorware

  6. Union Exemple 1 A={1,2,3,4,5,6} A B B={1,3,6,7,8,9} 1 1 3 2 6 3 7 4 8 5 6 9 A B = {1,2,3,4,5,6,7,8,9} OK

  7. Intersection Exemple 2 A={1,2,3,4,5,6} A B B={1,3,6,7,8,9} 1 1 3 2 6 3 7 4 8 5 9 6 OK A B = {1,3,6}

  8. Relative complement or difference of sets Exemple 3 A={1,2,3,4,5,6,7,9} B={1,3,6,7,8,9,10} A B 8 1 1 2 A – B = {2,4,5} 10 6 6 3 3 4 9 9 7 7 5 OK

  9. Relative complement or difference of sets Exemple 4 A={1,2,3,4,5,6,7,9} B={1,3,6,7,8,9,10} A B = {8,10} B – A 8 1 1 2 6 6 3 3 4 10 9 9 7 7 5 OK

  10. Complement Exemple 5 U U ={1,2,3,4,5,6,7,8,9,10} A={1,3,7,8,9} A 2 4 1 1 7 7 = {2,4,5,6,10} 8 8 3 3 10 6 9 9 5 OK

  11. Practice P 1 1. A = {2,4,6,8,9} B = { 1,2,3,4,5,6} {1,2,3,4,5,6,8,9} A B =……………… {2,4,6} A B =……………… 2. A = {4,6,8,9} B = { 1,2,3,5} {1,2,3,4,5,6,8,9} A B =……………… { } A B =……………… OK

  12. Practice 1.4 Page… 23 Home work 1.Which the following given that U = {1,2,3,4,5,6,7} draw a Venn diagrams 1) A = {2,3,7} 2) A = {3,4,5} and B = {1,3,5,7}

  13. Home work Practice 1.4 Page… 23 2) Given that U = {0,1,2,3,4,5,6,7,8} , A={0,2,4,6,8} B = {1,3,5,7} and C = {3,4,5.6}, Write the following in the set-tabular form
