The Learning Edge

From OSCON 2013: What do you need to know about prime numbers, Markov chains, graph theory, and the underpinnings of public key cryptography? Well, maybe more than you think! In this talk, we’ll explore the branch of mathematics that deals with separate, countable things. Most of the math we learn in school deals with real-valued […]

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 […]
