Sean los conjuntos
U = {1,2,3,4,5,6,7,8,9,10,11,12}
A = {2,3,5,6,8,9} B = {1,3,4,5,8,10} C = {2,3,5,4,7,9}
Representar gráficamente los anteriores conjuntos (en un solo esquema)
Decir si es Verdadero o Falso
i) 2 ∈ (A∩ C) ii) {3,8,5} = A∩B
iii){7,9} = C – B iv) (AUBUC)’ = {11,12}
Hallar:
A∩C
AUB=BUA
A={,2,3,5,6,8,9} B={1,3,4,5,8,10}
AUB={1,2,3,4,5,6}
BUA={4,5,6,1,2,3}
iii) (A-B) U (C – B)
i) 2 ∈ (A∩ C) verdadero
ii) {3,8,5} = A∩B verdadero
iii){7,9} = C – B falso falta el 2
iv) (AUBUC)’ = {11,12} verdadero
Hallar:
A∩C ={2,3,5,9}
AUB=BUA verdadero
A={,2,3,5,6,8,9} B={1,3,4,5,8,10}
AUB={1,2,3,4,5,6} falso
BUA={4,5,6,1,2,3} falso
iii) (A-B) U (C – B) ={2,6,9}U{2,7,9}={2,6,7,9}
