To solve for the proportion of odd numbers in the population, we first identify the odd numbers among the ages of the children in the population (which are 2, 3, and 10).

• The population: $\{2, 3, 10\}$
• Odd numbers: $3$

Step-by-step calculation:

1. Total number of values in the population = 3 (since we have ages 2, 3, and 10).
2. Number of odd numbers in the population = 1 (since only 3 is odd).

To find the proportion of odd numbers, we divide the number of odd numbers by the total number of values in the population: $\text{Proportion of odd numbers} = \frac{\text{Number of odd numbers}}{\text{Total population}} = \frac{1}{3}$

Thus, the proportion of odd numbers is: $\text{Proportion} = 0.333$

Final answer:

The proportion of odd numbers in the population is 0.333.
