Answer
$=\frac{4312}{31,593}\approx0.136$
Work Step by Step
We know that $probability=\frac{\text{number of favorable outcomes}}{\text{number of all outcomes}}$
The number of all outcomes is $31,593$.
The number of good outcomes is $4257+55=4312$ (females + males under 5)
Thus probability$=\frac{4312}{31,593}\approx0.136$
