In the economical field, mathematical expectation is one of the important digital characters of the
random variables. Many decision variables in economy problem are random variables; it is difficult to define
their concrete distribution. In this study, based on mathematical statistics method and finite difference theory,
we resolve the economical decision questions using the mathematical expectation. Moreover, the application
of mathematical expectation in economical question was analyzed by example from two aspects of investment
decision and sales profits. The results in our analysis show that mathematical expectation plays a great
application in production and sales profit.
Key words: Economic question, investment decision, mathematical expectation, sales profits, , ,
