Secondly, the combination in concept and problem teaching can enhance profound comprehension of Exclusive Events and Independent Events. Finally, because Distribution is basic knowledge in teaching probability, meanwhile, the calculation for Expected Value and Variance also are based on Distribution. Thus, Distribution is the most important in teaching them, it needs to give more emphasis.

其中计算机模拟手段在概率的频率定义教学中效果明显，并且直观模型在古典概型教学中的作用也相当明显；其次，通过概念教学与解题教学的结合可以帮助学生深刻理解互斥事件与独立事件；最后，随机变量的分布列作为概率基础知识，期望以及方差的计算都是以分布列为基础的，因而，强化分布列的教学是这部分内容的重中之重。

Studies on statistical properties of spontaneous spike trains of single auditory nerve have shown that the distributing patterns of interval in spike trains represent Poisson distribution. Since Poisson distribution is one of the simplest stochastic processes, previous studies on spontaneous spike trains of single auditory nerve were performed primarily by assuming them as stochastic processes. Recently, further studies on nonlinear dynamic system show that we have not enough evidence to demonstrate the process, whose distribution of probability density is exponential, is Poisson process.
