Answers
Hey there!
Here is your answer ↓↓
To solve the following problem, we will need to use the formula :
n(C ∪ T) = n(C) + n(T) - n(C ∩ T)
n ( C ∪ T ) = Number of people who like cricket or tennis
n ( C ) = Number of people who like cricket
n ( T ) = Number of people who like tennis
n ( C ∩ T ) = Number of people who like both cricket and tennis
Now, substituting in the formula : ↓↓→←↓⇅
100 = 60 + n ( T ) - 20
100 + 20 = 60 + n ( T )
120 - 60 = n ( T )
60 = n ( T )
The number of people who like to play tennis are 60

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
