Question

Considere os conjuntos A = { 0, 2, 4, 6, 8, 10}, B { 0, 1, 3, 5, 6, 7, 8, 11, 12} e C {2, 3, 5, 6, 7, 9}
O conjunto solução de ( A ∪ B ) ∩ C é igual a :
a.
{ 2, 3, 5, 6, 7 }
b.
{ 2, 3, 5, 6, 7, 9}
c.
{ 0, 6, 8 }
d.
{ }
e.
{ 0, 6, 7, 8 }

Answer 1

( A ∪ B ) ∩ C
(0,1,2,3,4,5,6,7,8,10,11,12) ∩ C
(0,1,2,3,4,5,6,7,8,10,11,12) ∩ (2,3,5,6,7,9)
= ( 2,3,5,6,7)

Alternativa A.
