Question

Dados os conjuntos A = {10, 12, 14, 16, 18 ,20, 21} e B = {11, 12, 13, 15, 18, 19, 20, 22, 24} determine A ∩ B.

A ∩ B = {11, 12, 13, 14}
A ∩ B = {10, 14, 16, 21}
A ∩ B = {11, 13, 15, 19, 22, 24}
A ∩ B = {10, 11, 12, 13, 14, 15, 16, 18, 19, 20, 21, 22, 24}
A ∩ B = {12, 18, 20}

Answer 1

A ∩ B = {12, 18, 20}
