7.6 Complement of Sets

The complement of a set A is the set of all elements in the universal set m and is denoted by Ac or A'.

Example:
If m = {1,2,3,4,5,6,7,8,9,10} and A = {1,3,5,7,9}, then find A'.
Solution:
The complement of A = m - A
That is, = {1,2,3,4,5,6,7,8,9,10} - {1,3,5,7,9}
A' = {2,4,6,8,10}.


Directions: Solve the following problems. Also write at least 5 examples of your own.
Q 1: If m = {1,2,3,4,5,6,7,8,9,10}, A = {2,4,6,8,10} and B = {1,3,5,7,9} then check the statement (A B)' = A' B'.
