We can find out by using the binomial distribution.

我们以使用二项分布找出答案。

And why this is called the binomial distribution.

以及为什么这被称为二项分布。

So this is why it's called a binomial distribution.

所以这就是它被称为二项分布原因。

Just like the binomial distribution is and the Poisson distribution, it's based on a bunch of parameters.

就像二项分布和泊松分布一样，它们都是基于一系列参数。

Why is this called a binomial distribution?

为什么这被称为二项分布？

That's what the binomial distribution tells us.

这就是二项分布告诉我们。

The probability for each value is given by what's called a binomial distribution, which peaks at the most likely outcome.

每个值概率由所谓二项式分布给出，该分布在最有能结果处达到峰值。

So you assume that a lot of things have-- well, in the discreet case, a binomial distribution.

所以你假设很多东西都有——嗯，在谨慎情况下， 二项分布。

“The Cartoon Guide to Statistics” promised readers they would chew over binomial distributions and conditional probability with the same ease with which they enjoyed Spider-Man.

那年一本名叫《统计卡通指南》书，承诺以让读者津津有味地习二项分布和条件概率，就像阅读《蜘蛛侠》一样轻松愉快。

And then I plot it and then I say what's the probability using the binomial distribution?

然后我将它绘制出来，然后用二项分布来说概率是多少？

There's also the binomial distribution and the normal distribution, which is what some people call the Gaussian or the bell curve.

还有二项分布和正态分布，也就是一些人所说高斯分布或钟形曲线。

Where, in this first one, we'll set up a model for the situation and start by talking about the binomial distribution.

在第一个例子中，我们将为这种情况建立一个模型，并首先讨论二项式分布。

I connected the lines but you see the binomial distribution look something more like this.

我连接了这些线条，但你以看到，二项分布看起来更像是这样。

In the binomial distribution, you say, oh, what is the probability of getting a 5?

在二项分布中， 你会问， 哦，得到5概率是多少？

The mean of the binomial distribution is essentially the probability of taking a left step times the total number of trials.

二项分布均值实质上等于采取左步概率乘以试验总次数。

And I calculate this probability -- I should have drawn maybe a line here -- I calculate this using the binomial distribution.

我计算这个概率——或许我应该在这里画一条线——我是通过二项分布来计算。

But in the binomial distribution you can kind of view it that way.

但在二项分布中，你以这样看待它。

So in any binomial distribution this is a probability that you get k successes.

因此，在任何二项分布中，这就是你获得k次成功概率。

This is what we did with the binomial distribution.

这就是我们在二项分布中所做。

What you're looking at right now, by the way, is known in the business as a binomial distribution, one of THE most fundamental distributions in probability.

顺便说一句，您现在看到在业界被称为二项分布，这是概率中最基本分布之一。
