A student watches TV every Sunday evening. Each week she chooses from a comedy, a reality show, or sporting e never chooses the same kind of program for 2 consecutive weeks. If she chooses a comedy one week, then she is choose one of the other programs the following week. If she watches a reality show one week, then she is 4 times a comedy as a sports program the next week. If she watches a sports program one week, then she is 3 times as likely as a reality show the next week. 1. Find the transition matrix for this Markov chain. 1/2 1/2 4/5 1/5

Question
A student watches TV every Sunday evening. Each week she chooses from a comedy, a reality show, or sporting event. This student
never chooses the same kind of program for 2 consecutive weeks. If she chooses a comedy one week, then she is equally likely to
choose one of the other programs the following week. If she watches a reality show one week, then she is 4 times as likely to watch a
comedy as a sports program the next week. If she watches a sports program one week, then she is 3 times as likely to watch a comedy
as a reality show the next week.
1. Find the transition matrix for this Markov chain.
1/2
1/2
4/5
1/5
3/4
1/4
2. Suppose this student's friends estimate that she is four times as likely to watch a comedy as a reality show and that she will
not be watching a sporting event. Find the probability vector representing this estimation.
4/5
1/5
3. What is the probability that she watches a sporting event two weeks from now?
23/40
4. What is the probability that she watches a comedy three weeks from now?
61/200
