1.	Give a example of equivalent set?
Answer» Two sets A and B are equivalent ifA is subset of Band B is a subset of AA={1,2,3}B={2,1,3}A=B<br>Definition 1: If two sets A and B have same cardinality, if there exists a objective function from Set A to B.Definition 2: Two sets A and B are said to be equivalent if they have the same cardinality i.e n(A) = n(B)A = {1, 2, 3} Here n(A) = 3\xa0B = {p, q, r} Here n(B) = 3\xa0Therefore, A ↔ B\xa0
