56% of families had no children under the age of 18;17% had no child;18% had two children;6% had three children; and 3% had four or more children. If a family is selected at random, find the probabilty that the family has less than three children(express your answer in percent form).
To find the probability that a family selected at random has less than three children, we need to add up the percentages of families that have zero children and families that have two children.
The given information tells us that 17% of families have no children, and 18% have two children.
Therefore, the probability that a family selected at random has less than three children is:
17% + 18% = 35%
So, the probability is 35%.
