Joint Probability Distributions In the section on probability distributions, we looked at discrete and continuous distributions but we only focused on single random variables. Probability distributions can, however, be applied to grouped random variables which gives rise to joint probability distributions. Here we're going to focus on 2-dimensional distributions (i.e. only two random... read more
