The probability of success in this example was 0.6, probability of failure was 0.4.

此示例中成功的概率为 0.6，失败的概率为 0.4。

And we know that our variance is essentially the probability of success times the probability of failure.

我们知道我们的方差本质上是成功概率乘以失败概率。

In the next video I'll do these with just general numbers where this is going to be p, where this is the probability of success and this is 1 minus p, which is the probability of failure.

在下一个视频中， 我将只用一般数字来做这些，其中 p 是成功的概率， 1 减去 p 是失败的概率。

So let's look at this, let's look at a population where the probability of success-- we'll define success as 1-- as having a probability of p, and the probability of failure, the probability of failure is 1 minus p.

所以让我们看看这个，让我们看看一个人口， 其中成功的概率——我们将成功定义为 1——具有 p 的概率， 而失败的概率， 失败的概率是 1 减去 p。
