Misalkan A = {1, 2, 3, …, 10} dan B = {3, 5, 7, 9,11, 13}, dan C = {7, 8, 9, 10, 11, 12, 13}. Tentukan anggota himpunan dari….
a. A – B
b. B – A
c. B – C
d. C – A
e. (A – B) ∩ (A – C)
f. (A – C) ∪ (B – C)
g. (A ∪ B) – (B ∪ C)
h. (A – B)c ∪ (B – C)c
Jawaban
a. A − B = {1, 2, 4, 6, 8, 10}
b. B − A = {11, 13}
c. B − C = {3, 5}
d. C − A = {11, 12, 13}
e. (A − B) ∩ (A − C) = {1, 2, 4, 6}
f. (A − C) ∪ (B − C) = {1, 2, 3, 4, 5, 6}
g. (A ∪ B) − (B ∪ C) = {1, 2, 4, 6}
h. (A − B)c ∪ (B − C)c = {3, 5, 7, 8, 9, 10, 11, 12, 13}
