Gamblers Ruin Problem A person repeatedly bets $1 each day. If he wins, he wins $1 (he receives his bet of $1 plus winnings of $1). He stops playing when he goes broke, or when he accumulates $3. His probability of winning is 0.4 and of losing is 0.6. What is the probability of eventually accumulating $3 if he starts with $1? With $2?

The following data were obtained from the admissions office of a 2-year junior college. Of the first-year class (F), 75% became sophomores (S) the next year and 25% dropped out (D). Of those who were sophomores during a particular year, 90% graduated (G) by the following year and 10% dropped out. (a) Set up a Markov chain with states D, F, G, and S that describes the situation. (b) How many states are absorbing? (c) Determine the matrix T. (d) Determine the probability that an entering first-year student will eventually graduate.

Gamblers Ruin Problem Colleen wants to purchase a $4000 used car, but has only $1000 available. Not wishing to finance the purchase, she makes a series of wagers in which the winnings equal whatever is bet. The probability of winning is 0.4 and the probability of losing is 0.6. In a daring strategy Colleen decides to bet all her money or at least enough to obtain $4000 until she loses everything or has $4000. That is, if she has $1000, she bets $1000; if she has $2000, she bets $2000; if she has $3000, she bets $1000. (a) What is the expected number of wagers placed before the game ends? (b) What is the probability that Colleen is wiped out? (c) What is the probability that Colleen wins the amount needed to purchase the car?

(a) Answer the questions in Problem 27 if the probability of winning is 0.5. (b) Answer the questions in Problem 27 if the probability of winning is 0.6.

Military Strategy Three armored cars, A, B, and C, are engaged in a three-way battle. Armored car A has probability of destroying its target, B has probability of destroying its target, and C has probability of destroying its target. The armored cars fire at the same time and each fires at the strongest opponent not yet destroyed. Using as states the surviving cars at any round, set up a Markov chain and answer the following questions: (a) How many states are in this chain? (b) How many are absorbing? (c) Find the expected number of rounds fired. (d) Find the probability that A survives.

We assume the following learning pattern exists: If the mouse is in room 2, 3, or 4, it moves with equal probability to any room the maze permits; if it is in room 1, it gets caught in the trap and remains there; if it is in room 5, it remains in that room with the cheese forever. (a) Construct the transition matrix P. (b) How many rooms represent an absorbing state for this Markov chain?
