## The Definition of Finite Sequences and Matrices of Probability, and Addition of Matrices of Real Elements

In this article, we first define finite sequences of probability distribution and matrices of joint probability and conditional probability. We discuss also the concept of marginal probability. Further, we describe some theorems of matrices of real elements including quadratic form.
