Answer:
c. Stock A
Explanation:
The future expected value of each stock is given by the sum of each possible outcome multiplied by its correspondent likelihood.
For Stock A, the expected value is:
[tex]E(A) = \$12*0.5+\$10*0.5\\E(A) =\$11[/tex]
For Stock B, the expected value is:
[tex]E(B) = \$15*0.5+\$7*0.5\\E(B) =\$11[/tex]
Both stocks have the same expected value, so it would be reasonable to assume that the investor could pick any of the two options. However, since A has a lower associated risk (Worst case scenario is better than stock B), the investor should choose stock A.
