Suppose that two investments have the same three payoffs, but the probability associated with each payoff differs, as illustrated in the table below:
PAYOFF

0.30
|
$250
|
0.80

a. Find the expected return and standard deviation of each investment.
b. Jill has the utility function U = 5I, where I denotes the payoff. Which investment will she choose?
c. Ken has the utility function U = 51I. Which investment will he choose?
d. Laura has the utility function U = 5I2. Which invest- ment will she choose?
