Question 402214: Hi I am trying to figure out an average pertaining to blood group antigens ex:
24% of Caucasians are negative for the blood group antigen
8% of blacks are negative for the blood group antigen
if 12% of the population is black, how would I figure the percentage of the general population that is negative for the blood group antigen?

8% of 12% of the population PLUS 24% of 88% of the population

[.08(12%)] + [.24(88%)]
