### High School Mathematics7.2 Intersection of Sets

 The intersection of sets A and B is the set of elements which are common to A and B. Example: If A = {1, 2, 3, 4} and B = {2, 4, 6}, then find A Ç B. Solution: Given that, A = {1, 2, 3, 4} and B = {2, 4, 6}. A Ç B = {1, 2, 3, 4} Ç {2, 4, 6} The common elements in A and B are 2 and 4. Therefore, A Ç B = {2, 4}. Directions: Choose the correct answer. Also write at least 5 examples of your own.
