Permutations and Probability
... When finding probabilities of groups, what is the effect of specifying that order matters? Order distinguishes between groups with the same set of elements. For example, AB is not the same as BA if order matters, but it is the same if order does not matter. This affects numbers of outcomes, which af ...

But, the probability model for the sum of two random variables is not necessarily the same as the model we started with even when the variables are indepe ...
