solution

Make a Venn diagram to solve the problem.

I like to use markers

I like to use colored pencils

3 children like to use both markers and colored pencils. Put 3 dots in the area that is in both circles.

I like to use markers

I like to use colored pencils

Now add dots to the other two areas until there are 7 dots in the "I like to use markers" circle and 5 dots in the "I like to use colored pencils" circle.

I like to use markers

I like to use colored pencils

Count the dots that are in the "I like to use markers" circle but are not in the "I like to use colored pencils" circle. There are 4 dots.

4 children like to use markers but not colored pencils.
