Question

Fie multimile: A= { 1;2;3;3;5}, B= {0;2;4;6;8} si C= { 1;3;5;6;7;9} Detrminati:

a) A∪B, A∪C, B∪C, ( A∪B)∪C;

b) A∩B, B∩C, C∩A, ( A∩B)∩C

AM NEVOIE URGENT! ESTE PENTRU LUNI!

Answer 1

a) AUB=(0, 1 ,2,3,4,5,6,8)
AUC=(1,2,3,5,6,7,9)
BUC=(0,1,2,3,4,5,6,7,8,9)
b) A∩B=(2)
B∩C=(6)
C∩A=(1, 3, 5)
( A∩B)∩C=2∩C=> MULTIMEA VIDA
