# In a survey of 60

Total number of People n(P) = 60.

n(H) =25.

n(T) = 26.

n(I) = 26.

n (H I) = 9

n (H T) = 11

n (T I) = 8

n (H T I) = 3

The people who read at least one newspaper would be n(H or I or T) = n(HIT)

We know,

n(HIT) = n(H)+n(I)+n(T) – n (H I)– n (H T)– n (T I)+ n (H T I)

n(HIT) = 25+26+26–9–11–8+3

n(HIT) = 52.

There are 52 people who read at least one newspaper.
