Answer 2

Calculation of the Number of People in the Group

To determine the number of people in the group, we need to add the number of people collecting coins and the number of people collecting stamps.

Given: - 20 people collect coins. - 25 people collect stamps. - 14 people collect both coins and stamps.

To find the total number of people in the group, we can add the number of people collecting coins and the number of people collecting stamps, and then subtract the number of people collecting both coins and stamps.

Calculation: - Number of people collecting coins: 20 - Number of people collecting stamps: 25 - Number of people collecting both coins and stamps: 14

Therefore, the number of people in the group is 20 + 25 - 14 = 31.

So, there are 31 people in the group.
