Idon't know how to set this a 2002 loyola university of chicago study showed a marked decrease in blue-eyed americans. about one-half of americans were born in 1900 with blue eyes. by 1950 that number had dropped to one-third. the 2000 census states that only about 1 of every 6 americans had blue eyes. if the rate of decrease continues at the same rate as the prior 50 years, what fraction of people will be born with blue eyes by the year 2050?
