原声例句
可汗学院:统计学(视频版)

And this also applies to the discrete probability distributions.

这也适用于离散概率分布。

可汗学院:统计学(视频版)

So since we're sampling from a discrete distribution it's actually going to be a discrete distribution, but it's going to have 100 possible values.

因此,由于我们从离散分布中采样,它实际上将是一个离散分布,但它将具有 100 个可能的值。

可汗学院:统计学(视频版)

And for a discrete distribution like this, your mean or you're expected value is just going to be the probability weighted sum of the different values that your distribution can take on.

对于这样的离散分布,您的均值或期望值将只是您的分布可以采用的不同值的概率加权和。

可汗学院:统计学(视频版)

It's hard to kind of have a good intuition for a discrete distribution because you really can't take on those values, but it makes sense that the distribution is skewed to the right over here.

很难对离散分布有很好的直觉,因为你真的不能接受这些值,但分布在这里向右倾斜是有道理的。
