When a family is selected at random, the probability that it has some children is #96%# or #0.96#.

Explanation:

As #6%# families have #1# child,

#38%# families have #2# children,

#42%# families have #3# children and

#10%# families have more than #3# children,

This means that #6%+38%+42%+10%=96%# have one or more children

Hence, when a family is selected at random, the probability that it has some children is #96%# or #0.96#.
