CONCEPT TO BE IMPLEMENTED

SET :

A set is a well defined collection of distinct objects of our perception or of our thought to be conceived as a whole

Representation of Set :

A set can be represented in following ways

(i) Statement form method

(ii) Roster or tabular form method

(iii) Rule or set builder form method

EVALUATION

We know that for any set A the complement of A is denoted by A' and defined as

A' = { x ∈ U : x ∉ A }

Here it is given that ,

Universal set = U = { 3 , 7 }

A = { 3 , 7 }

We see that all elements of A are in U

Thus A = U

Hence the required set

= A'

= { x ∈ U : x ∉ A }

= Φ

FINAL ANSWER

If U = { 3 , 7 } , A = { 3 , 7 } then A' = Φ
