  In this paper, we connect four different branches of Mathematics: Statistics,
Probability, Algebra and Discrete Mathematics with the objective of introducing
new results on Markov chains and evolution algebras obtained by following a
relatively new line of research, already dealt with by several authors. It
consists of the use of certain directed graphs to facilitate the study of
Markov chains and evolution algebras, as well as to use each of the three
objects to make easier the study of the other two.
