Question

Exercițiul 9 vă rog!

Answer 1

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!
