Adjusting the bin numbers

Let's take our first steps away from the default number of bins with our histograms. We'll start by building a histogram of the percentage of the speed a driver is traveling over the limit for each citation. This is calculated as ((speed - speed_limit) / speed_limit)*100.

Plot percentage over the speed limit as a histogram with the number of bins set to 40. While you're at it, set the alpha to 0.8. You're entirely on your own with this one, no scaffolding.
