So the thing that I hope jumps out at you from this picture is no great guesses about figuring out this is a ?, so if the probability that the goalie's going to jump to the right is less than a ?, then the best you can do is represented by this green line, which is shoot to the right.

我希望大家都能从图中看出来,得出这一点的横坐标是?不难,如果门将扑向右路的概率,小于?的时候,此时你的最佳策略用这段绿线表示,即你应该从右路射门

That's great, but it's still not quite the picture we need, because actually, - all the electrons are not in equal orbitals -- one's in an s orbital, and 3 are in p.

这很好，但这还不是我们想要的图像，因为实际上，所有的电子不是在相同的轨道里的-,一个在s轨道里，3个在p轨道里。
