9) A={1,2,4,7,8} B={0,1,3,4,5} C={2,4,6,8} D={1,3,5,7,9}
E={0,1,2,3,4,8}
Calculati:
•A U B = {0,1,2,3,4,5,7,8}
•B U C = {0,1,2,3,4,5,6,8}
•C U E = {0,1,2,3,4,6,8}
•B U C U D ={0,1,2,3,4,5,6,7,8,9}
•B intersectat C = {4}
•A intersectat E = {1,2,4,8}
•D intersectat E = {1,3}
•A\B = {2,7,8}
•B\C= {0,1,3,5}
•D\E = {5,7,9}
•E\C = {0,1,3}
•B\A = {0,3,5}
•(A U B) intersectat C = {0,1,2,3,4,5,7,8} intersectat {2,4,6,8}
=> {2,4,8}
•(B U C) intersectat (A U E) = {0,1,2,3,4,5,6,8} intersectat
{0,1,2,3,4,7,8} =>
{0,1,2,3,4,8}
•(A U B U C) intersectat ( C U D U E) = (0,1,2,3,4,5,6,7,8)
intersectat (0,1,2,3,4,5,6,7,8,9) => {0,1,2,3,4,5,6,7,8}
Succes!
