List out some sets A and B and choose their elements such that A and B are disjoint.

If A and B are disjoint sets,then

If A and B are two sets such that A ⊂ B , then what is A ∪ B ?

If two-empty sets A and B have n elements in common, then show that AxxB and BxxA have n^(2) elements in common.

Prove that if A,B are any sets then A-B, A cap B and B-A are mutually disjoint.

Write down the following statements in set-theoretic notations: P and Q are disjoint sets.

Let A and B be two non empty subsets of set X such that A is not a subset of B, then: (a) A is a subset of complement of B (b) B is a subset of A (c) A and B are disjoint sets (d) A and complement of B are non-disjoint sets

If A and B are two finite sets and n(A)=5,n(B)=6 then the minimum number of elements of the set A cup B is

Three sets A, B, C are such that A=BnnC and B=CnnA , then

Match List I with List II and choose the correct answer

If A and B are two sets then A cap (A cap B) equals
