Statistics

I'm taking an night class on Statistics at the UC Berkeley Extension, as part of my general "Preparation For A Degree That, For Some Reason, I Believe I Need To Get Before I'll Be Offered The Exact Job I Already Have" program. Below, for your amusement, an excerpt from last week's class. All you need to know in advance is that, when you're dealing with probability, you refer figuratively to whatever population you're picking from as the "box."

Prof. Jurkat: So, the first step is to draw the box with the different results. Then, second, we need to determine the proportion of those results in the box...like so. Does anybody know the third step?

Alek: [raising hand] Step Three...um, make her open the box?
