| Abstract: | In this paper,a mathematical expectation identity on the minimal order statistic is presented and proved by means of the probabiUstic methods,inspired by a mathematical expectation identity on the maximal order statistic.These two identities are supplement and extension about knowledge of the probability theory. |
