Question

Dados os conjuntos A = {10, 13, 14, 15, 16, 17, 18}, B = {12, 14, 15, 16, 19} e C = {10, 13, 16, 19, 20}, determine:  
(A união B), 
(A união C),
 (A interseção B),
(A interseção C)
 (A interseção B) união C,

 (A interseção B) interseção C.

Answer 1

AuB = {10, 12, 13, 14, 15, 16, 17, 18}
AuC = {10, 13, 14, 15, 16, 18, 19, 20}
AпB = {14, 15, 16}
AпC = {10, 13, 16}
(AпB)uC = {10, 13, 14, 15, 16, 19, 20}
(AпB)uB = {10, 20, 13, 14, 15, 16, 19}
(AпB)пC = {16}

Answer 2

AuB = {10, 12, 13, 14, 15, 16, 17, 18}
AuC = {10, 13, 14, 15, 16, 18, 19, 20}
AпB = {14, 15, 16}
AпC = {10, 13, 16}
(AпB)uC = {10, 13, 14, 15, 16, 19, 20}
(AпB)uB = {10, 20, 13, 14, 15, 16, 19}
(AпB)пC = {16}∈
