Answer

Explanation:

Step1: Recall probability formula

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$.

Step2: Identify values

The number of favorable outcomes (number of seven - year - olds) is 4, and the total number of outcomes (total number of children) is 18.

Step3: Calculate probability

$P(\text{seven - year - old})=\frac{4}{18}=\frac{2}{9}$

Answer:

$\frac{2}{9}$
