A random number will be generated to determine if a row will be selected or not (similar to flipping a coin with a probability of P/100).

将生成一个随机数来确定是否选择一行（类似于以 P/100 的概率扔钱币）。

So, if I kind of circle where the probability gets somewhat substantial here, you can see we're much closer to the nucleus at the s orbital than we are for the p, then when we are for the d.

我把概率,很大的地方圈出来，你们可以看到在s轨道上,比p轨道更接近原子核，最远是d轨道。

The P-value is the probability of obtaining a result at least as extreme as the one that was actually observed, given that the null hypothesis is true.

值就是当原假设为真时，比所得到的样本观察结果更极端的结果出现的概率。

py And finally, we can look at the 2 p y, so the highest probability is going to be along the y-axis.

最后我们来看一下，概率密度最高的是沿着ｙ轴。

So what we can say is look at each of these separately, so if we start with looking at the 2 p z orbital, the highest probability of finding an electron in the 2 p z orbital, is going to be along this z-axis.

我们可以来分别看看这些图，首先来看看2pz轨道，在2pz轨道里,找到电子的最大概率，是沿着ｚ轴。
