In this problem there are 8 children.

There are also 15 + 17 + 8 = 40 people.

Therefore, if one person is chosen at random, there is a 8 / 40 probability that this person is a child.

This fraction can be simplified by dividing each side by 8: 8 /40 = 1 / 5.

Therefore the answer is 1/5 which can also be written as 0.2 as a decimal; both are correct.
