Alison Schafer has been the coolest "teach" yet in Math. While I loved my previous two profs (crazy-fun Jessica Knapp, and sweet-patient Laurie Varecka), this one is goofy and actually makes probability, random variables and cumulative distributive functions interesting!
Yes, math can be fun. Here's two actual quiz questions (she makes her own quizzes... can you tell?!):
1. James Bond is heading to the Tropicana Night Club in Las Vegas to track down Dr. MathDoom. He is arranging transportation and needs to know how big of a vehicle he needs to plan for in order to hold the number of girls he'll be bringing home with him for coffee at the end of the night. The table shows the number of girls and the probabilities from the past of that many happening. Based on this data, how many girls does James Bond expect to go home with? Compute this showing the proper notation and your work.
2. You are entered into the "Who's the Biggest Bling Daddy" contest. There are three other contestants: P. Diddy, Paris Hilton's dog, and Will Ferrell. The bookies are saying the odds of you winning are 28%. Paris Hilton's Dog has a 0.32 probability of winning. The other two contestants have equal probabilities. You've just found out that Paris Hilton's dog is disqualified for not being human! What is the new probability that you will win, given that her dog is no longer in the competition? Write the proper mathematical notation for this probability.
She claims she stayed up until 1 in the morning playing Grand Theft Auto in order to create the database of 100 stolen cars which we used for the Excel DCOUNT function on the midterm exam!
I feel I did pretty good on the final exam, but I've been wrong about that feeling too many times to trust it now! However, going into the last day of class (Monday), it feels pretty good to see a 97% next to my code name!

That's great the way your teacher writes her own quizzes and does it with so much creativity and fun. I must admit, though, that when it comes to math my brain just shuts down. I need to go back to simple arithmetic and re-learn everything, I know.
I think it's a real accomplishment to have such a good grade, too! I always knew you were one smart cookie.

Way to go!
