## 2.20 Assortative Mating**Assortative mating** is a nonrandom mating pattern where individuals with similar genotypes and/or phenotypes mate with one another more frequently than what would be expected under a random mating pattern. Researchers studying this topic collected data on eye colors of 214 Scandinavian men and their female partners. The table below summarizes the results (rows represent male eye color while columns represent female eye color). For simplicity, we only include heterosexual relationships in this exercise.*(please round any numerical answers to 4 decimal places)*| | Blue | Brown | Green | Total ||----------|------|-------|-------|-------|| **Blue** | 62 | 22 | 28 | 112 || **Brown**| 12 | 19 | 18 | 49 || **Green**| 14 | 11 | 28 | 53 || **Total**| 88 | 52 | 74 | 214 |### Questions:a) What is the probability that a randomly chosen male respondent or his partner has blue eyes? [__]b) What is the probability that a randomly chosen male respondent with blue eyes has a partner with blue eyes? [__]c) What is the probability that a randomly chosen male respondent with brown eyes has a partner with blue eyes?

Eleven percent of American children (ages 4 to 17) have Attention Deficient Hyperactivity Disorder (ADHD) according to the Center for Disease Control. Suppose six American children in this age group are randomly selected, is the probability that at least one has ADHD unusual? No, this probability is not unusual because it is more than 0.05. Yes, this probability is unusual because it is more than 0.05. No, this probability is not unusual because it is within 2 standard deviations of the mean. Yes, this probability is unusual because it is not within 2 standard deviations of the mean. No, this probability is not unusual because it is more than 0.01.
