People like A=n(A)=21
People like B=n(B)=26
People like C=n(C)=29
People like both A and B=n(A{intersection}B)=14
People like both A and C=n(A{intersection}C)=12
People like both B and C=n(B{intersection}C)=14
People like  A,B and C=n(A{intersection}B{intersection}C)=8
people who like only C=n(C)-n(A{intersection}C)-n(B{intersection}C)+n(A{intersection}B{intersection}C=29-12-14+8=11
