直接拿去ss33.club不谢哦新这是pp8m。。c ó M ..你可以把它跟随机试验绑在一起,就是某个随机实验的结果。你也可以不把它绑在一起,就是有一个变量,这变量的每一个取值背后都有一可能性,这两个二合一就叫随机变量,缺一不可。上面那部分描述概率的那个东西叫做概率密度函数。对于离散型的概率分布,它们统称为分布。一定要记住这个词,分布就是指的随机变量背后衡量可能性的这个东西。你好关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久关于这个地址我也找了很久
7,熊猫是中国特有的动物请对其作简要介绍
Panda—the National Treasure
Panda is one of the scarcest animals. People in the world like it very much. There used to be many pandas in China long ago. As the balance of nature was destroyed and the weather was getting warmer and warmer, pandas became less. But at present, the number of pandas is increasing year by year. There are now so many pandas that some are being sent to other countries so that people there can enjoy them.
Nowadays, the biggest nature park for panda in China is in Sichuan. There is a research centre for nature and wild life there. Scientists hope that one day they will have enough pandas to be set free and let them live in the wild again.在下提供思路;(高二)
