What is the probability that a random UHF algebra is of infinite type? What is the proba-bility that a random simple AI algebra has at most k extremal traces? What is the expected value of the radius of comparison of a random Villadsen-type AH algebra? What is the prob-ability that such an algebra is Z-stable? What is the probability that a random Cuntz-Krieger algebra is purely infinite and simple, and what can be said about the distribution of its K- theory? By constructing C*-algebras associated with suitable random (walks on) graphs, we provide context in which these are meaningful questions with computable answers.
