Well, recall that very basic building block we introduced 1 last week which allowed you to grab a random number between 1 and 10 or 1 or a hundred.
好吧，让我们先回想一下上周介绍过的,能产生1~10之间，或者1~100之间随机数的1,基本构建块。

So it comes up with a random number then they asked for the answer.
随后出现一个随机数,然后他们再追问答案
-
On the whole, Yale students are not random number generators.
总的来说,耶鲁大学的学生不是随机数生成器
-
Do any of you look like a random number generator?
你们有人是随机数生成器吗
-
You spin this big wheel and it rotates for a while and then it stops at one number, but obviously a random number, because this wheel of fortune had all the numbers from zero to one hundred.
你转动那个大轮盘,它会旋转一会儿,最后停在一个数字上,显然是一个随机数,因为幸运轮盘可以指向,0到100的的任何数
-
The point here is when you're playing a game, you want to think about what other people are trying to do, to try and predict what they're trying to do, and it's not necessarily a great starting point to assume that the people around you are random number generators.
这里的要点是当你在进行游戏时,你想要推测出其他人的想法,想要推测出他们可能的选择,假设别人是随机数生成器可不是,一个很好的出发点
-
If you have an experiment and the outcome of the experiment is a number, then a random variable is the number that comes from the experiment.
如果你有一个试验,这个试验的结果是一个数,那么相对应的随机变量,指的就是这个试验结果所对应的那个数
-
For example, the experiment could be tossing a coin, I will call the outcome heads the number one, and I'll call the outcome tails the number zero, so I've just defined a random variable.
比方说,抛硬币的试验,我将正面向上的结果对应数字1,反面向上的结果对应数字0,这样我就定义了一个随机变量
-
You have discrete random variables, like the one I just defined, or there are also--which take on only a finite number of values-- and we have continuous random variables that can take on any number of values along a continuum.
就像刚定义的,是一个离散型随机变量,随机变量还可以有无限种取值,也就是连续型随机变量,随机变量可以取某一区间的一切值
-
I have it down that there might be an infinite number of possible values for the random variable x.
对于这个随机变量X,可能的取值个数是无限的
