I couldn't help it. I had to take a picture of our blackboard at the end the 3-hour Probability and Statistics class. This is what school is all about: blackboards, chalk, and some very confused people (me included).
I love probability and statistics, but after being out of school for 12 years, my knowledge is a bit rusty in this area. Sometimes my brain gets so confused that coin tosses appear less random then they really are, confidence intervals are... hmm, not so confident about them, and normal distributions are anything but normal. Arghhh, it hurts! My notebook is full of notes like these:

Time to scrape that rust and get to work. I've got some catching up to do.
