... Operations on Set ... Let U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}, A = {1, 2, 3, 4, 5, 6}, B = {2, 4, 5, 6}, and C = {1, 6, 7}. Find: (A ∪ B) ∩ (A ∪ C) ????? Answer: {1, 2, 3, 4, 5, 6} Step-by-step explanation: (A ∪ B) ∩ (A ∪ C) Substitute: ({1, 2, 3, 4, 5, 6} ∪ {2, 4, 5, 6}) ∩ ({1, 2, 3, 4, 5, 6} ∪ {1, 6, 7}) {1, 2, 3, 4, 5, 6} ∩ ({1, 2, 3, 4, 5, 6} ∪ {1, 6, 7}) {1, 2, 3, 4, 5, 6} ∩ {1, 2, 3, 4, 5, 6, 7} {1, 2, 3, 4, 5, 6}
