a. How many people seeing only Indians film?
b. How many people seeing both Chinese and US based film?

To find the number of people seeing only Indians films, we need to subtract the number of people who have seen multiple films from the total number of people who have seen Indian films.

a. Number of people seeing only Indian films:
= Total number of people seeing Indian films - Number of people seeing both Indian and US films - Number of people seeing both Indian and Chinese films
= 75 - 45 - 34
= 41

Therefore, 41 people have seen only Indian films.

To find the number of people seeing both Chinese and US films, we can follow a similar approach.

b. Number of people seeing both Chinese and US films:
= Total number of people seeing both Chinese and US films - Number of people seeing all three films
= 26 - 3
= 23

Therefore, 23 people have seen both Chinese and US films.
