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
This is our desired answer.
