Question
About half of Americans born around 1920 had blue eyes. By mid-century that number dropped to a third. Immigration patterns, intermarriage, and genetics all play a part in the decline. While the drop-off has been happening for a century, the plunge in the past few decades has taken place at a remarkably high rate. Today only about one 1 of every 6 Americans has blue eyes. In Finland about 89% of the population has blue eyes. (meets objectives: g, h) What is the probability that two unrelated people standing in line at WAWA will both have blue eyes?
Explanation / Answer
Solution:
Question: What is the probability that two unrelated people standing in line at WAWA will both have blue eyes?

Therefore, Probability that 2 unrelated people both have blue eyes= (1/6)x(1/6) = 1/36
