Damn the Bernoulli variables!!!

I messed up on my test. According to my review sheet (above), I memorized the justifications for the derivation that is shown, but the question on the exam asked us to DO the actual DERIVATION and didn't mention the justifications. So I drew a nice little design and handed in my test.

I think I did okay on the other stuff, but only time will tell. I'll let you know how I did after spring break, which my brain officially went on today.

Oh, and to make today extra-special, I just found out that BOTH of my funding applications for next year were rejected. I think I'll just crawl under a rock now, back where I belong.
