E. Sifat - Sifat Operasi Himpunan
Sifat Komutatif
Misalkan A dan B adalah himpunan, maka berlaku
A ∪ B = B ∪ A
A ∩ B = B ∩ A
Diperoleh: Diperoleh:
A = {0,2, 6} P = {m, n}
B = {1, 2, 5} Q = {e, f, g}
A ∪ B = {0, 1, 2, 5, 6} P ∪ Q = (m, n, e, f, g)
B ∪ A = {0, 1, 2, 5, 6} Q ∪ P = (m, n, e, f, g)
A ∩ B = {2} P ∩ Q = Ø
B ∩ A = {2} Q ∩ P = Ø
Ternyata: Ternyata:
A ∪ B = B ∪ A P ∪ Q = Q ∪ P
A ∩ B = B ∩ A P ∩ Q = Q ∩ P
