It's somewhat different when we're talking about the p or the d orbitals, and we won't go into the equation there, but this will give you an idea of what we're really talking about with this radial probability distribution.
当我们讨论p轨道或者,d轨道的时候会有些不同,我们那时不会给出方程,但它会给你们一个,关于径向概率,分布的概念。
If you follow through from the independent theory, there's one of the basic relations in probability theory-- it's called the binomial distribution.
如果继续往下看,在概率论里有一个基本的概念,叫做二项分布
Last time we looked at the notion, last lecture we looked at the idea of a distribution.
上一次我们看过这个概念,上一次讲座中我们看到了概率分布的概念。
I want to emphasize that it hasn't always been that way and that probability is really a concept that arose in the 1600s.
我想说,概率的表述并非一贯如此,这个概念成型于十七世纪
You're not going to need to know a lot about this for this course, but this is--I wanted to get the basic ideas down.
对于本门课程来说,你不必,对刚才讲的概率的知识有很深入的了解,我只想介绍一些概率论的基本概念
Another important concept in probability theory that we will use a lot is expected value, the mean, or average-- those are all roughly interchangeable concepts.
概率论中另外一个常用的重要的概念是,期望值或者也叫均值,这两个概念可以互换
We're also going to recognize, however, that insurance got a slow start because-- I believe it is because-- people could not understand the concept of probability.
不管怎么说,我们得承认,保险起步缓慢,因为...,我相信是因为...,人们无法理解概率的概念
We have instead what's called a probability density when we have continuous random variables.
所以我们用概率密度的概念来描述,连续型随机变量的情况
One of the first principles of probability is the idea of independence.
概率论中最基本的一个原则,就是独立性的概念
I want to start with the concept of probability.
我想从概率的概念开始讲起
So that's the basic idea.
这是概率论中最基本的概念
