प्रश्न
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.
उत्तर
All the students of a class is an Universal set i.e.
U = set of all the students of a class and
A = set of the students who secure 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.
