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 204 Scandinavian men and their female partners. The table below summarizes the results. For simplicity, we only include heterosexual relationships in this exercise.69

1. (a) What is the probability that a randomly chosen male respondent or his partner has blue eyes?
