Question

Let {Xn, n ≥ 0} be a Markov chain with three states 0, 1, 2 and has the transition probability matrix,

P= [ 3/4  1/4  0

       1/4  1/2  1/4

       0  3/4  1/4 ]

 

The initial distribution is, P {Xn; n = 0, 1, 2} = 1/3

a. What is P {X1 = 1| X0 = 2}?
b. What is P {X2 = 2| X1 = 1}?
c. What is P {X2 = 2, X1 = 1| X0 = 2}?
d. What is P {X2 = 2, X1 = 1, X0 = 2}?
e. What is P {X3 = 1, X2 = 2, X1 = 1, X0 = 2}?
