In a survey of 60 people, it was found that 25 people read newspaper H. 26 read newspaper T, 26 read newspaper I, 9 read both H and I, 11 read both H and T, 8 read both T and I, 3 read all three newspaper. Find:
(i) the number of people who read at least one of the newspapers.
(ii) the number of people who read exactly one newspaper.

Explanation

To solve the problem, we will use the principle of inclusion-exclusion to find the number of people who read at least one newspaper and the number of people who read exactly one newspaper.

### Given Data:
- Total number of people surveyed, \( n = 60 \)
- Number of people reading newspaper H, \( n(H) = 25 \)
- Number of people reading newspaper T, \( n(T) = 26 \)
- Number of people reading newspaper I, \( n(I) = 26 \)
- Number of people reading both H and I, \( n(H \cap I) = 9 \)
