【Abstract】 There are many various ways to prove equalities and limit equations. This paper provides the proof of some equalities and limit equations by the ways of constructing probability model; thus relevant knowledge in probability theory and other branches of mathematics, and relevant knowledge in higher mathematics and elementary mathematics are connected; and the ways for solving the problems of this sort are enriched. The extension and superiority of probability methods in application are showed.更多还原
