Answer 2

To solve this problem, let's analyze the given information step by step.

Given Information:

- There are 5 boys in class 4A. - Some boys play volleyball, while others play football. - 3 boys play both football and volleyball.

Analysis:

Let's represent the boys who play football with the letter "F" and the boys who play volleyball with the letter "V". The boys who play both sports will be represented by "FV".

Based on the given information, we can create a diagram to represent the situation:

F: __ __ __
V: __ __ __

We know that there are 5 boys in total, so we can fill in the diagram accordingly:

F: __ __ __
V: __ __ __

We also know that 3 boys play both football and volleyball. Let's fill that in:

F: __ __ __
V: __ __ __
   FV FV FV

Now, we need to determine how many boys play only football and how many play only volleyball. To do this, we subtract the number of boys who play both sports from the total number of boys playing each sport.

There are 7 boys playing football, and 3 of them play both sports. So, the number of boys playing only football is 7 - 3 = 4.

Similarly, there are 5 boys playing volleyball, and 3 of them play both sports. So, the number of boys playing only volleyball is 5 - 3 = 2.

Answer:

Therefore, in class 4A, 4 boys play only football, and 2 boys play only volleyball.
