Calculating the Number of Students Who Haven't Read Either Book

To calculate the number of students who haven't read either "War and Peace" or "Crime and Punishment," we can use the principle of inclusion and exclusion.

Let's denote: - A as the number of students who read "War and Peace" (25 students). - B as the number of students who read "Crime and Punishment" (22 students). - C as the number of students who read both books (10 students).

We can use the formula: Total students who read at least one book = A + B - C Then, the number of students who haven't read either book = Total students in the class - (A + B - C)

Calculation

Using the given data: - A = 25 (students who read "War and Peace") - B = 22 (students who read "Crime and Punishment") - C = 10 (students who read both books) - Total students in the class = 40

We can calculate: Total students who read at least one book = 25 + 22 - 10 = 37 Number of students who haven't read either book = 40 - 37 = 3

Therefore, 3 students haven't read either "War and Peace" or "Crime and Punishment."
