If A = {3, 5, 7, 9, 11}, B = {7, 9, 11, 13}, C = {11, 13, 15} and D = {15, 17}; find
B ∩ C
उत्तर
Here, A = {3, 5, 7, 9, 11}, B = {7, 9, 11, 13}, C = {11, 13, 15}, D = {15, 17}
B ∩ C = {7, 9, 11, 13} ∩ {11, 13, 15}
= {11, 13}

Show that the following four conditions are equivalent:
- A ⊂ B
- A – B = Φ
- A ∪ B = B
- A ∩ B = A
Using properties of sets show that A ∪ (A ∩ B) = A
Using properties of sets show that A ∩ (A ∪ B) = A.
Show that A ∩ B = A ∩ C need not imply B = C.
Let A and B be sets. If A ∩ X = B ∩ X = Φ and A ∪ X = B ∪ X for some set X, show that A = B.
(Hints A = A ∩ (A ∪ X), B = B ∩ (B ∪ X) and use distributive law)
