Monroe is retired and has $4.2 million of financial assets. One of Monroe's goals is to fund expected nominal expenditures of $120,000 in each of the next three years at a 95% required probability of success. Thompson suggests using a goals-based approach to construct a portfolio that meets this goal. She identifies a set of three available optimized sub-portfolio modules, as shown in Exhibit 1. She assumes that each year's expenditures will be a single year-end cash outflow.老师，为什么这题只需要考虑95%的收益，不需要考虑期望收益和波动率？这个是考哪个知识点呢？
