A∪B={1,2,3,4,5,6,7,8}, A∪C={1,2,3,4,5,6,7,8}, A∪D={1,2,3,4,5,6,7,8}, B∪C={1,2,3,4,5,7}, B∪D={1,3,4,5,6,7}, C∪D={1,2,3,4,5,6,7}
Pembahasan
a. A∪B = {1, 2, 3, 4, 5, 6, 7, 8} ∪ {1, 3, 5, 7} = {1, 2, 3, 4, 5, 6, 7, 8} b. A∪C = {1, 2, 3, 4, 5, 6, 7, 8} ∪ {1, 2, 3, 4} = {1, 2, 3, 4, 5, 6, 7, 8} c. A∪D = {1, 2, 3, 4, 5, 6, 7, 8} ∪ {4, 5, 6, 7} = {1, 2, 3, 4, 5, 6, 7, 8} d. B∪C = {1, 3, 5, 7} ∪ {1, 2, 3, 4} = {1, 2, 3, 4, 5, 7} e. B∪D = {1, 3, 5, 7} ∪ {4, 5, 6, 7} = {1, 3, 4, 5, 6, 7} f. C∪D = {1, 2, 3, 4} ∪ {4, 5, 6, 7} = {1, 2, 3, 4, 5, 6, 7}
