6.81 On April 1, 2010, the Bureau of the Census in the United States attempted to count every U.S. resident.

Suppose that the counts in the table for Exercise 6.81 at the top of the next page are obtained for four counties in one region.

a. If one person is selected at random from this region, what is the estimated probability that the selected person is from Ventura County?

b. If one person is selected at random from Ventura County, what is the estimated probability that the selected person is Hispanic?

c. If one Hispanic person is selected at random from this region, what is the estimated probability that the selected individual is from Ventura County?

d. If one person is selected at random from this region, what is the estimated probability that the selected person is an Asian from San Luis Obispo County?

e. If one person is selected at random from this region, what is the estimated probability that the person is either Asian or from San Luis Obispo County?

f. If one person is selected at random from this region, what is the estimated probability that the person is Asian or from San Luis Obispo County but not both?
g. If two people are selected at random from this region, what is the estimated probability that both are Caucasians?
h. If two people are selected at random from this region, what is the estimated probability that neither is Caucasian?
i. If two people are selected at random from this region, what is the estimated probability that exactly one is a Caucasian?
j. If two people are selected at random from this region, what is the estimated probability that both are residents of the same county?
k. If two people are selected at random from this region, what is the estimated probability that both are from different racial/ethnic groups?
