Distribution of Amir's sales

Since each deal Amir worked on (both won and lost) was different, each was worth a different amount of money. These values are stored in the amount column of amir_deals As part of Amir's performance review, you want to be able to estimate the probability of him selling different amounts, but before you can do this, you'll need to determine what kind of distribution the amount variable follows.

Both dplyr and ggplot2 libraries are loaded and amir_deals is available.
