Find the probability of each e-sports mentioned. Also check whether probability of each e- sports mentioned is 1 or not.​

Answer 1

Answer:

Let 'A' be the set of students who play cricket, 'B' be the set of students who play tennis.

It is given that, n(A)=25, n(B)=20 and n(A∩B)=10= students who play both the games 

Thus n(A∪B)=n(A)+n(B)−n(A∩B)=20+25−10=35

Therefore the students who play neither of the cricket and tennis =60−35=25

Answer 2

Answer:

Correct option is D)

Let 'A' be the set of students who play cricket, 'B' be the set of students who play tennis.

It is given that, n(A)=25, n(B)=20 and n(A∩B)=10= students who play both the games 

Thus n(A∪B)=n(A)+n(B)−n(A∩B)=20+25−10=35

Therefore the students who play neither of the cricket and tennis =60−35=25
