Calculation of the Number of Students Who Did Not Subscribe to Any Magazine

To determine the number of students who did not subscribe to any magazine, we need to subtract the number of students who subscribed to at least one magazine from the total number of students.

Given: - Total number of students: 100 - Number of students who subscribed to the "Barvinok" magazine: 48 - Number of students who subscribed to the "Solntse" magazine: 34 - Number of students who subscribed to both magazines: 27

To calculate the number of students who did not subscribe to any magazine, we can use the principle of inclusion-exclusion.

Let's break down the calculation step by step:

1. Start with the total number of students: 100. 2. Subtract the number of students who subscribed to the "Barvinok" magazine: 100 - 48 = 52. 3. Subtract the number of students who subscribed to the "Solntse" magazine: 52 - 34 = 18. 4. Add back the number of students who subscribed to both magazines, as they were counted twice in the previous steps: 18 + 27 = 45.

Therefore, 45 students did not subscribe to either magazine.
