通过Excel表格的展示，我们可以发现第一个题目是二项分布和第二个题目

通过Excel表格的展示，我们可以发现第一个题目是二项分布和第二个题目是正态分布。由于分布的类型不同，他们的公式和处理方法不同。比如二项分布，我们可以采用公式法进行计算。E（X）=NP，V（X）=NP（1-P）来求得我们想要的均值和方差。而对于正态分布，我们可以现将其标准化，在进行计算得出范围值。也可以进行逆运算，就像第二题的最后一问。学习这门课以后，我们可以熟练掌握相关技巧去解决二项分布和正态分布的问题。

Through the display of Excel table, we can find that the first topic is binomial distribution and the second topic is normal distribution. Due to different types of distribution, their formulas and processing methods are different. For example, binomial distribution can be calculated by formula method. E (x) = NP, V (x) = NP (1-p) to find the mean and variance we want. For normal distribution, we can standardize it now and calculate the range value. You can also perform inverse operations, like the last question of the second question. After learning this course, we can master relevant skills to solve the problems of binomial distribution and normal distribution.
