D. What is meon rat in having three rooms labeled 1, 2, and 3, as shown in Figure 4.6. The age trained to select a door at random and move from one room to a bell is rung. 18. A psychologist conducts an experiment on rats. She puts a to are nother when A. Build the transition matrix, T, of the given Markov chain, B. If a rat is initially in roo m 3, what is the probability that this rat will be in room 2 after the bell has rung five times? C. What is the long-term behavior of this Markov chain? Determine vector and interpret it. Mod Disc Let a, age cl linear This near h FIGURE 4.6. A cage with three rooms and five doors
