Question

If U = {1,2,3,4,5,6,7,8} and A = {2,3,4,6,8} then complement of set A is ..............
1.{1,35,7}
2.{1,2,3,4,5,6,7,8}
3.{1,5,7}
4.{2,3,4,6,8}
​

Answer 1

Complement of Set A => { 1, 5, 7 }

Answer 2

Answer:

A' =U-A

A' = {1,2,3,4,5,6,7,8} - {2,3,4,6,8}

A'={1,5,7}

Therefore, complement of set A is {1,5,7}
