Answer:

ANSWER

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

Accordingly,

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

The Venn diagram for the given problem can be drawn as above.

It can be seen that number of people who like product C only is

=29–(4+8+6)=11
