Write some sets A and B such that A and B are disjoint.

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

Two sets A and B are said to be disjoint if

If a set A has 5 elements , then the number of ways of selecting two subsets P and Q from A such that P and Q are mutually disjoint is

The sets A-B, B-A and A cap B are mutually disjoint sets. Use examples to observe if this is true.

IF A,B are disjoint sets such that n(A)=4 and n(A cup B)=7, then n(B)=………….

From the following Venn diagram. Write the elements of the sets of A and B. and verify n ( A cup B )+n( A cap B )= n(A)+n(B).

For any sets A and B, show that P ( A ∩ B ) = P ( A ) ∩ P ( B ) .

IF A and B are two sets such that A subset B then, What is A cup B ?
