Stochastic matrix

A stochastic matrix is a type of matrix that is used for describing the probabilities of different things happening. It is kind of like a big chart that shows the chances of different things happening and how likely it is that one specific thing will happen. Think of it like a game of chances. The rows in the matrix represent the different things that could happen and the columns show how likely it is that each of these things will happen.
