Question

In a group of people 100 people 60 people like to cricket 20 people like to play both cricket and tennis. How many people like to play tennis, but not a cricket

Answer 1

Answer:

Step-by-step explanation:

100 people are there.

People who like to play only tennis is equal to-

100-(people who like to play cricket+people who like to play both)

=100-(60+20)

=100-80

=20

So, 20 people like to play only tennis.

Answer 2

ANSWER

P(cricket)=P(A)=60

P(cricket & tennis)=P(A∩B)=20

P(total)=P(A∪B)=100

P(A∪B)=P(A)+P(B)−P(A∩B)

100=60+P(B)−20

P(B)=60

P(tennis but not cricket)=P(tennis)-P(both tennis and cricket)

=60−20=40
