Now with this definition of this-- and this is the most general definition of a Bernoulli Distribution.
现在有了这个定义——这是伯努利分布最一般的定义。

To figure out really the formulas for the mean and the variance of a Bernoulli Distribution if we don't have the actual numbers.
如果我们没有实际数字,要真正找出伯努利分布的均值和方差的公式。

And then we'll come up with general formulas for the mean and variance and standard deviation of this distribution, which is actually called the Bernoulli Distribution.
然后我们会得出这个分布的均值、方差和标准差的通用公式,这实际上被称为伯努利分布。

And if you do that with a Bernoulli Distribution, we learned in the video on Bernoulli Distributions, that the mean of this distribution right here is going to be equal to p.
