(i) A ∩ B
(ii) A ∩ C
(iii) B ∩ C
(iv) B ∩ D
(v) B ∩ (C ∪ D)
(vi) A ∩ (B ∪ C)
Given; A = {3, 5, 7, 9, 11}, B = {7, 9, 11, 13} and C = {11, 13, 15}, and D = {15, 17}
(i) A ∩ B = {7, 9, 11}
(ii) A ∩ C = {11}
(iii) B ∩ C = {11, 13}
(iv) B ∩ D = Φ or {}
(v) B ∩ (C ∪ D) = {11, 13}
(vi) A ∩ (B ∪ C) = {7, 9, 11}
