11-60.

In a certain town, $45\%$ of the population has dimples and $70\%$ has a widow’s peak (a hairline above the forehead that makes a “V” shape). Assuming that these physical traits are independently distributed, what is the probability that a randomly selected person has both dimples and a widow’s peak? What is the probability that he or she will have neither? Use a generic area model or a tree diagram to represent this situation.
