Question

E={0,2,4,6,8,10,12,14}calculati:
A={0,1,2,3,4,}
B={3,4,5,6,7}
C={6,7,8,9}
D={0,5,10,15,20}

a=AU(întors)B
b=AU(întors)C
c=BU(întors)C
d=CU(întors)D
e=DU(întors)E
f=CU(întors)E
g=BU(întors)E​

Answer 1

A intersectat B = {3, 4}

A intersectat C = {vid}

B intersectat C = {6, 7}

C intersectat D = {vid}

D intersectat E = {0, 10}

C intersectat E = {6, 8}

B intersectat E = {4, 6}
