Answer 2

26. a) A={1,3,4,6,8,9}
B={2,4,5,6,7,9}
b) A={1,6,8,9}
c) B={2,5,6,7,9}
28. a) A={1,2,3,4}
B={5,6,7,8}
b) A={1,2,3,4,5,6,7,8}
B={3,4,5,6,7,8,}
A intersectat cu B = {3,4,5,6,7,8}
A\(A intersectat B)={1,2,3,4,5,6,7,8}\{3,4,5,6,7,8}={1,2}
c) A={1,2,3,4,5,6}
B={1,2,3,4,5,6,7,8}
A intersectat B={1,2,3,4,5,6}
