Answer 1

Answer:

complement of the set is the no. of students in the class securing less than 50% percent marks.

Answer 2

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 percent or more marks in maths as follows

A=(students who obtained 50 percent or more marks in maths)

Now we have to find the complement of A

it can be calculated as

A'=U-A

A=(All the students in the class obtained less than 50 percent marks)
