Question

All 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

Answer 1

compiment of A is the students who score 50/ or less

Answer 2

Answer:

A' = {All the students in the class obtained less than 50 percent marks}

Step-by-step explanation:

Given that

All students of a class represent a universal set. Therefore, this condition can be translated into maths as

U = {All students of the class}

A set represent the set of those students who secured 50% or more marks in maths. This statment can be translated into maths as follows

A = {Students who obtained 50% or more marks in maths}

Now we have to find the complement of A. The complement of A is represented by A' and it can be calculated as

A' = U - A

A' = {All the students in the class obtained less than 50 percent marks}

This is our desired answer.
