Discrete Probability Distributions: Example Problems (Binomial, Poisson, Hypergeometric, Geometric)

I work through a few probability examples based on some common discrete probability distributions (binomial, Poisson, hypergeometric, geometric -- but not necessarily in this order). I assume that you've been previously introduced to these distributions (although this isn't necessary for the geometric problem, as the probability is easily calculated from basic probability rules). Students sometimes have difficulty determining the appropriate distribution to use, so this video may give some help with the proper thought process.
