a. Find the steady-state vector for the Markov chain in Exercise 3.
b. What is the probability that after many days a specific student is ill? Does it matter if that person is ill today?

Data from in Exercise 3

On any given day, a student is either healthy or ill. Of the  students who are healthy today, 95% will be healthy tomorrow.  Of the students who are ill today, 55% will still be ill tomorrow.
