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 ÇB 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 A^{1} 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 Î M > True Monday Î 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 Ç B = {3,7} Directions: Solve the following problems. Also write at least five examples of your own.
