In my previous article, I’ve been talking about two of the most popular probability distributions of discrete random variables: Bernoulli and Binomial. Here, I’m going dwell on their so-called ‘counterparts’, which are Geometric and Inverse Binomial.

Both of them concerns the idea of a sequence of Bernoulli trials, hence it is worth it to recall when we are facing a Bernoulli random experiment.
