You play a game. you start with a score of zero. if your score becomes negative, you lose. if your score goes above 1, you win. if your score is zero, there’s a 10 % chance your score will go down (and you will lose), a 10 % chance your score will stay the same, and an 80 % your score will go up to 1. if your score is 1, there’s a 20 % chance your score will go down to zero, a 10 % chance your score will stay at 1, and a 70 % your score will go up (and you will win). if you represent this as a 4-state markov chain, what is the stochastic matrix p?
