In this lesson, you'll look at a way to represent discrete distributions - the probability mass function (PMF), which maps from each value to its probability. A probability mass function (PMF), ...

Your plot should look like this: Hints: You will need call .plot.bar twice, and pass in ax, so that both plots use the same axes; Change the parameter alpha to adjust the transparency; If you don't ...

The above image is a representation of the probability mass function where the conditions that state “all the values must be positive and sum up to 1” are followed. Probability density function: This ...

This web calculator allows users to specify the Poisson parameter (λ) and number of occurrences (x). After finishing the steps, the calculator will show a plot of the probability mass function (pmf) ...
