9. Załączniki - w pierwszym same figury, w drugim rozwiązanie 10. A={1,2,3,4,5,6,7,8,9,10} B={1,3,5,7,9} C={2,5,8,10} D={2,4,7,9} A∪B = {1,2,3,4,5,6,7,8,9,10}=A A∩B={1,3,5,7,9} = B A B  = {2,4,6,8,10} B A = ∅ A∪C = {1,2,3,4,5,6,7,8,9,10}=A A∩C = {2,5,8,10} = C A C  = {1,3,4,6,7,9} C A = ∅ A∪D = {1,2,3,4,5,6,7,8,9,10}=A A∩D = {2,4,7,9} = D A D  = {1,3,5,6,8,10} D A = ∅ B∪C = {1,2,3,5,7,8,9,10} B∩C = {5} B C  = {1,3,7,9} C B = {2,8,10} B∪D = {1,2,3,4,5,7,9} B∩D = {7,9} B D  = {1,3,5} D B = {2,4} C∪D = {2,4,5,7,8,9,10} C∩D = {2} C D  = {5,8,10} C B = {4,7,9}
