Question

Let all the students of a class is an Universal set. Let set A be the students who secure 50% or more marks in Maths. Then write the complement of set A.1

Answer 1

We have,

U = set of all the students of a class and A = set of the students who secure 50% or more marks in Maths

So, the complement of set A, A' = U $-$ A = set of the students who secure less than 50% marks in Maths.
