6.60 In early 2001, the U.S. Census Bureau started releasing
the results of the 2000 census. Among many
other pieces of information, the bureau recorded
the race or ethnicity of the residents of every county
in every state. From these results, the bureau calculated
a “diversity index” that measures the probability
that two people chosen at random are of different
races or ethnicities. Suppose that the census determined
that in a county in Wisconsin 80% of its residents
are white, 15% are black, and 5% are Asian.
Calculate the diversity index for this county.
