Chapter 3. Excercise 3.2 #112

Closed mlsmall closed 2 years ago

mlsmall commented 6 years ago

The exercise states: "Write functions called PmfMean and PmfVar that take a Pmf object and compute the mean and variance"

What is the solution? How do we write these functions?

I should have put solutions in chap03soln.ipynb, but it looks like I didn't. I'll do that when I have a chance.

In the meantime, check out: https://github.com/AllenDowney/ThinkStats2/blob/master/code/thinkstats2.py#L546
