1. Assume that the probability ofhaving sickle cell anemia is 0.15 and the probability of beingAfrican-American is 0.45 in a given population. Additionally,assume the joint probability of having sickle cell anemia and beingAfrican-American in this population is 0.13. A) What is the probability of having sickle cell anemia, giventhat you are African-American in this given population? B) Suppose we know that the probability of having sickle cellanemia, given that you are Asian-American is 0.21. What can we sayabout the relative risk of sickle cell anemia in African-Americansversus Asian Americans? Interpret this result. . . .
