# Assignment 3

- Make up an interesting (or entertaining) example showing that
Pr(x|y) can be very different from Pr(y|x). (Should take 5 minutes)

- Use the definition of conditional probability to derive Bayes's
Theorem. It may be a while since you used your high-school algebra,
but that's all this requires. (If you have not completed this
in 10 minutes, don't bother doing it, just look at the solution when
I give it out.)

- Do Exercise 6.1 in Jurafsky and Martin. That is, show the
formula for the maximum likelihood estimate of probability in a
trigram model (Should take 5-10 minutes)
