tolong bantu bsk d kumpulin

Saya mengasumsikan bahwa:
A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
B = {3, 5, 7, 9, 11, 13}
C = {7, 8, 9, 10, 11, 12, 13}
Maka:
a. {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} - {3, 5, 7, 9, 11, 13} = {1, 2, 4, 6, 8, 10}
b. {3, 5, 7, 9, 11, 13} - {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} = {11, 13}
c. {3, 5, 7, 9, 11, 13} - {7, 8, 9, 10, 11, 12, 13} = {3, 5}
d. {7, 8, 9, 10, 11, 12, 13} - {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} = {11, 12, 13}
e.
1. {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} - {7, 8, 9, 10, 11, 12, 13} = {1, 2, 3, 4, 5, 6}
2. {1, 2, 4, 6, 8, 10} ∩ {1, 2, 3, 4, 5, 6} = {1, 2, 4, 6}
f. {1, 2, 3, 4, 5, 6} ∪ {3, 5} = {1, 2, 3, 4, 5, 6}
g.
1. {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} ∪ {3, 5, 7, 9, 11, 13} = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 13}
2. {3, 5, 7, 9, 11, 13} ∪ {7, 8, 9, 10, 11, 12, 13} = {3, 5, 7, 8, 9, 10, 11, 12, 13}
3. {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 13} - {3, 5, 7, 8, 9, 10, 11, 12, 13} = {1, 2, 4, 6}
h.
1. Komplemen dari {1, 2, 4, 6, 8, 10} adalah {3, 5, 7, 9, 11, 13}
2. Komplemen dari {3, 5} adalah {7, 8, 9, 10, 11, 12, 13}
3. Maka, {3, 5, 7, 9, 11, 13} ∪ {7, 8, 9, 10, 11, 12, 13} = {3, 5, 7, 8, 9, 10, 11, 12, 13}

yang bagian h saya kurang mengerti. Jadi kalau salah mohon dimaafkan
