There are three genes in the gene pool for blood, A, B, and O. Two of these three are present in a person's blood: A and B dominate O, whereas A and B are codominant. This gives the following possibilities:
Genotype
Phenotype
AAtype A bloodAOtype A bloodABtype AB bloodBOtype B bloodBBtype B bloodOOtype O bloodLet p, q, and r represent the frequencies of the genes A, B, and O in the blood gene pool. Suppose a certain population has 40% type A, 37% type B, and 23% type O. Construct a Punnett square and find (p + q + r) 2 to answer, what percent of the population has each genotype.
A. AA = 16%, AO = 18.4%, AB = 29.6%, BO = 19.02%, BB = 12.69%, OO = 4.29%
B. AA = 16%, AO = 19.4%, AB = 30.6%, BO = 15.02%, BB = 13.69%, OO = 3.29%
C. AA = 18%, AO = 19.4%, AB = 30.6%, BO = 16.02%, BB = 12.69%, OO = 3.29%
D. AA = 17%, AO = 20.4%, AB = 30.6%, BO = 16.02%, BB = 12.69%, OO = 3.29%
E. AA = 16%, AO = 18.4%, AB = 29.6%, BO = 17.02%, BB = 13.69%, OO = 5.29%

Find the expected value.Mr. Cameron is sponsoring an summer concert. He estimates that he will make $300,000 if it does not rain and make $60,000 if it does rain. The weather bureau predicts the chance of rain is 0.34 for the day of the concert. An insurance company is willing to insure the concert for $150,000 against rain for a premium of $30,000. If he buys this policy, what are his expected earnings from the concert?
A. $180,000 B. $300,000 C. $270,000 D. $239,400
