Question

Se dau multimile : A={1,2,3,4,5,6,7} B={5,6,7,8,9} C= {1,2,3,7,12} Aflati :
a). A reunit B
b). A intersectat C
c). A\B
d). A reunit C
e). B intersectat C
f). B\C
g). B reunit C
h). A reunit B reunit C
i). A\C
j). A intersectat B
k). A intersectat B intersectat C
l). A reunit (B intersectatC)

Se considera multimile : A= {1,2} B={1,2,5} C= {4,6} efectuati:
a). (A reunit B) intersectat C
b). A reunit ( B intersectat C)
c). C\ ( A reunitB)
Daca mai vreti exercitii puteti sa imi scrieti!

Answer 2

A U B={1,2,3,4,5,6,7,8,9}
A intersectat cu C={1,2,3,7}
A/B={1,2,3,4}
A U C={1,2,3,4,5,6,7,12}
B INTERSECTAt CU C={7}
B/C={5,6,8,9]
A U B  U C={1,2,3,4,5,6,7,8,9,12}
A/C={4,5,6}
A INTERSECTAT CU B={5,6,7}
A INTERSECTAT CU B INTERSECTAT CU C ={7}
A U (B INTERSECTAT CU C)={1,2,3,4,5,6,7}
(A U B) INTERSECTAT CU C= MULTIMEA VIDA
A U (B INTERSECTAT CU C =MULTIMEA VIDA
C/(A U B)=MULTIMEA VIDA
