Well, not the movies. I was in times square at a peep show.

不是电影 我当时在时代广场看表演。

So that's going to be m squared x1 squared, plus 2 times mx1 times b plus b squared.

所以这将是 m 平方 x1 平方加上 2 乘以 mx1 乘以 b 加上 b 平方。

So that's 6 factorial over 3 factorial times 6 minus 3 factorial times this part-- 0.7 third time's 0.3 squared.

所以这是 6 阶乘 3 阶乘乘以 6 减去 3 阶乘乘以这部分——0.7 第三次的 0.3 的平方。

So what's in the parentheses right here, this is the exact same thing as negative 1 squared times y plus the expected value of negative y.

那么这里括号中的内容，这与负 1 的平方乘以 y 加上负 y 的期望值完全相同。

In other words, if we turn our square right two times, then right once, that's the same as once, then twice, or for numbers, one plus two is the same as two plus one.

换句话说，如果我们将正方形向右转两次， 然后向右转一次，这与一次，然后两次相同，或者对于数字， 一加二等于二加一。

Well, I like to write it this way, it easier to remember, times whatever value you're trying to get minus the mean of our distribution divided by the standard deviation of our distribution squared.

好吧，我喜欢这样写， 这样更容易记住，乘以你试图得到的任何值减去我们的分布均值除以我们的分布平方的标准差。
