Question

Q2. In a group of 70 people, 37 like coffee, 52 like tea and each person likes at
least one of the two drinks. How many people like both coffee and tea?

Answer 1

Answer:

18 people like both coffee and tea

Step-by-step explanation:

(A union B) = n (A) + n (B) - n (A intersection B)

n(A union B) = Total number of people

n (A) = People who like Tea = 52

n(B) = People who like Coffee = 37

n ( A intersection B) = People who like Tea and coffee both

 

From the formula, n (A intersection B) = 52 + 37 - 70 = 19

People who like coffee only and not tea = n(B) - n ( A intersection B) = 37 - 19 = 18
