Question

please solve 24 with steps

Answer 1

Answer:

Step-by-step explanation:

Let A, B, and C be the set of people who like product A, B, and C respectively. 

n(A) = 21, n(B) = 26, n(C) = 29, n(A ∩ B) = 14, n(C ∩ A) = 12, n(B ∩ C) = 14, n(A ∩ B ∩ C) = 8 

People who many liked product C only 

= n(C) - n(C ∩ A) - n(B ∩ C) + n(A ∩ B ∩ C) 

= 29 -12 – 14 + 8 

= 11 

Hence, 11 liked product C only.
