Consider an experiment with n possible states. At each step, individuals transition from state i to state j with probability sij. (This sort of model is useful in computer science, economics, statistics, and other areas.) Let S be the matrix with entries sij. This matrix satisfies: (i) all entries are ≥ 0, and (ii) all rows sum to 1. Matrices satisfying properties (i) and (ii) are called stochastic matrices. An example is ( (a) For the given example S, find S² and S3, and verify that they are also stochastic S= 2
