Contoh soal

Diketahui

A = { 2, 4, 6, 8, 10 } C = { 2, 3, 5, 7 }

B = { 1, 3, 5, 7, 9 } D = { 2, 6, 8 }

Tentukan himpunan dari:

1) B – C 4) A – D

2) A – B 5) D – A

3) B – A

Penyelesaian

1. B – C = { 1, 3, 5, 7, 9 } - { 2, 3, 5, 7 } = { 1, 9 }

2. A – B = { 2, 4, 6, 8, 10 } - { 1, 3, 5, 7, 9} = { 2, 4, 6, 8, 10 }

3. B – A = { 1, 3, 5, 7, 9 } - { 2, 4, 6, 8, 10} = { 1, 3, 5, 7, 9 }

4. A – D = { 2, 4, 6, 8, 10 } - { 2, 6, 8 } = { 4, 10 }

5. D – A = { 2, 6, 8 } - { 2, 4, 6, 8, 10 } = { } atau ∅
