IN A CLASS OF 60 STUDENTS, 25 PLAYS BASKETBALL, 2O PLAY VOLLEYBALL, AND 10 STUDENTS PLAY BOTH OF THEM. HOW MANY STUDENTS PLAY NEITHER BASKETBALL NOR VOLLEYBALL?

25

Step-by-step explanation:

We'll compare it with the study of sets, the most noticeable operation of which is:

where,

n(A ∪ B) is the Union Set, i. e, the set that contains all the elements

n(A) is a subset of the Union Set

n(B) is another subset of the Union Set, and

n(A ∩ B) is the Intersection Set ,i.e, the set contains common elements from both A and B sets.

Let set A contains the students who play basketball and set B, the students who play Volleyball.

10 students play both of them, i. e.,

Using the above operation:

=> n(A ∪ B) = n(A) + n(B) - n(A ∩ B)

=> n(A ∪ B) = 25 + 20 - 10

=> n(A ∪ B) = 35

The total number of students in the class

= students into the given sports + students who don't play any of them

The students who play neither = 60 - 35

= 25

answer: a and b
