Answer 2

Answer:

Step-by-step explanation:

Let 'F' and 'M' represent folk and modern song respectively.

n(U) = 200

n(F) = 130

n(M) = 110

n(F∩M) = 70

Let n(A) = no. of people who don't like both songs = x

Representing above info. in venn diagram,

[Note: Venn diagram given at the end]

From venn diagram,

n(u) = n(F) + n(S) +n(A) - n(F∩M)

or, 200 = 130 +110 +x - 70

or, 200 - 170 = x

∴x = 30

∴30 people don't like both songs
