Calculating the Number of Students Not Interested in Collecting

To calculate the number of students not interested in collecting, we can use the given information about the number of students collecting stickers, coins, or both.

Let's start by calculating the number of students interested in collecting: - Stickers: 26 students - Coins: 37 students - Both stickers and coins: 20 students

To find the total number of students interested in collecting, we can add these numbers together: 26 (collecting stickers) + 37 (collecting coins) - 20 (collecting both stickers and coins) = 43

Now, to find the number of students not interested in collecting, we subtract the total number of students interested in collecting from the total number of students: 60 (total students) - 43 (interested in collecting) = 17

Therefore, 17 students are not interested in collecting.
