And here's my green line representing my expected payoff as the shooter, from shooting to the right, as a function of the probability that the goalie dives to the right.

这条绿线表示作为一个罚球球员,我从右路射门的收益,是门将扑向右路概率的一个函数

The green line is the building costs and you can see that building costs, since 1890, in real terms-- everything is corrected for inflation -have gone up a little bit since 1890, but not a whole lot.

绿线表示了建筑成本,你可以看到建筑成本,自1890年来,以实际值计算,所有的数据均进行了通胀修正,从1890年开始有一点点上涨,并非是大幅度上涨

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
