问题如下：
A financial planner has created the following data to illustrate the application of utility theory to portfolio selection:
If an investor’s utility function is expressed as and the measure for risk aversion has a value of 2, the risk-averse investor is most likely to choose:
选项：
A.Investment 1.
B.Investment 2.
C.Investment 3.
解释：
B is correct.
Investment 2 provides the highest utility value (0.1836) for a risk-averse investor who has a measure of risk aversion equal to 2.
在计算器上按19%-（8%²）时，得怎么按结果才对。
我按19然后%，减去，括号，8，%，这时候结果就不对了，必须按完括号按0.08，再按²，然后括号，才能得到正确值。
就是括号里的百分数必须自己计算，用%键值就不对。
