4.49 Sets - Basic Operations - Union, Intersection and Compliment

There are 3 basic operations we can perform on a set.
1) Union: Combine two sets A and B to get their Union written as A U B and read as A is a union of B or A union B.
2) Intersection: Find what 2 sets A and B have in common written as A B and read as A is an intersection of B or A intersects B.
3) Compliment: To find out what is in the universal set but not in the given set A, and is written as A1 and read as A compliment or A prime.

Example:
If M is a set of months in a year, indicate whether the following statements are True or False.
M = {January, February} -----> False since it is not a complete set of monts in a year.
February M -----> True
Monday M ----> False

Example:
A = {1,2,3,4,5,6,7} and B = {3,7,8}
A U B = {1,2,3,4,5,6,7,8}
A B = {3,7}
