Question

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

Answer 1

Answer:

40

Step-by-step explanation:

let people who play cricket be x and those who like to play tennis be y.

x=60

x intersection y=20

y - x intersection y= x union y - x

=100-60

=40

Answer 2

Answer:

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
