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
