UNIVERSAL SET -

 

A set that contains all sets in a given context is called the “Universal Set”. The universal set is usually denoted by U, and all its subsets by the letters A, B, C, etc.

- wherein

R is the universal set of N,W and Z.

 

 There is no common portion between A and A', hence A \cap A' = \phi

 


Option 1)

A\cup A^{c}=U

Option 2)

A\cap A^{c}=U

Option 3)

U-A=A^{c}

Option 4)
