If the proportion of an African population that are susceptible to Malaria is 0.37, what proportion of the population are affected with Sickle Cell Anemia? A. 0.18 B. 0.63 C. 0.11 D. 0.154 E. 0.255

Solution

Proportion of population susceptible to malaria= p²= .37

so p= 0.608

since p+q=1, so q=1-0.608=0.392

proportion of the population affected with Sickle Cell Anemia= q²+2pq=0.392²+(2*0.608*0.392)

=0.154+0.477

=0.631

So the answer is option B
