Question

Dados os conjuntos:
a-{10,12,13,14,15}=
b-{14,15,16,17,18,19,20}=
c-{6,7,8,9,10,11}=
pede-se:
a-AuB=
b-A^B=
c-AuC=
d-A^C=
e-AuC=
f-B^C=
g-AuBuC=
h-A^B^C=

Answer 1

A U B = {10, 12, 13, 14, 15, 16, 17, 18, 19, 20}
A ^ B = {14, 15}
A U C = {6, 7, 8, 9, 10, 11, 12, 13, 14, 15}
A ^ C = {10}
B ^ C = conjunto vazio { }
A U B U C = {6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 18, 20}
A ^ B ^ C = conjunto vazio { }
