In an example presented earlier in this chapter, we noted that, in the united states in 1986, 13.6% of all individuals were poor, 9.3% of all individuals were poor whites (thus 4.3% were poor nonwhites), and 84.8% of all individuals were white (thus 15.2% were nonwhite). from these data we determined that 11.0% of whites were poor and 28.3% of nonwhites were poor. now, suppose that we pick a poor person at random from this population. what is the probability that he or she is nonwhite?
