Make a PMF

The GSS dataset has been pre-loaded for you into a DataFrame called gss. You can explore it in the IPython Shell to get familiar with it.

In this exercise, you'll focus on one variable in this dataset, 'year', which represents the year each respondent was interviewed.

The Pmf class you saw in the video has already been created for you. You can access it outside of DataCamp via the empiricaldist library.
