Complement of a setDefinition
The complement of a set are the elements found in the set. It is denoted by C or I on the set. That is, AC, AI.
Ex: a) given that ε
= {1, 2, 3, …, 10} and A = {2. 4. 6, 8, 10}, find the complement of A
b) Given that U
= {a, b, c, d, e} and B = {a, c}, find BC
Solution: a) AC = {1, 3, 5, 7, 9}, b) BC = {b, d, e}
