Answer 2

Answer:

Step-by-step explanation:

Let,

A=denotes the sets who preferred x products

B=denotes the sets who preferred y products

Now,

Given,

(AUB)=200,  n(A)=102,  n(B)=125,  n(AintersectionB)=?

We all know that

n(AUB)=n(A)+n(B)-n(A∩B)

200=102+125-n(A∩B)

n(A∩B)=102+125-200

            =227-200

            =27
