Question

im a class 35 student, each student like to play either cricket or hockey, 24 students like to play cricket and 5 students like to play both the game how many students play hockey​

Answer 1

Answer:

16.

Step-by-step explanation:

Here, let A be the set of students who likes to play cricket and B be the set of students who likes to play football.

As per question: n(A∪B)=35

n(A)=24

n(A∩B)=5

We know, n(A∪B)=n(A)+n(B)−n(A∩B)

⇒n(B)=n(A∪B)−n(A)+n(A∩B)

=35−24+5

=16

Hence number of students who like to play football =16.
