Problem Statement:

A group of students is studying English and French. There are 15 students studying English and 12 students studying French. Additionally, 7 students are studying both languages. The task is to determine the total number of students in the group.

Solution:

To find the total number of students in the group, we need to add the number of students studying English, the number of students studying French, and subtract the number of students studying both languages.

Let's calculate it step by step:

1. Number of students studying English: 15. 2. Number of students studying French: 12. 3. Number of students studying both English and French: 7.

To find the total number of students in the group, we can use the principle of inclusion-exclusion. According to this principle, we add the number of students studying English and French and then subtract the number of students studying both languages to avoid double counting.

Total number of students = Number of students studying English + Number of students studying French - Number of students studying both languages

Total number of students = 15 + 12 - 7

Total number of students = 20

Therefore, there are a total of 20 students in the group.
