John and Lauren are looking for a good neighborhood to raise their children. They want neighbors who have kids and who are fellow rollerbladers as well. The couple surveys a random sample of residents in a nice-looking neighborhood. Their results are shown below.

David, Anastasia, and Miles live in the neighborhood. David is focusing on his career and does not have children. Anastasia has never rollerbladed. All we know about Miles is that he is very tall.

Calculate the following probabilities based on the frequency table below.
Round to the nearest hundredth of a percent.

Probability that David is a rollerblader $=$equals $\%$percent
Probability that Anastasia does not have kids $=$equals $\%$percent
