Typo in 02_bayes.ipynb

[edavishydro]

In the Review section, text is:

"For example, here's the probability that a respondent is a Democrat, given that they are liberal."

The code in cell 15 is:
conditional(female, banker)

instead of:
conditional(democrat, liberal)

The next sentence/code cell has a similar error.

Fixed. Thanks!
