Answer:
A) distribution of x2 = ( 0.4167 0.25 0.3333 )
B) steady state distribution = 
Step-by-step explanation:
Hello attached is the detailed solution for problems A and B
A) distribution states for A ,B, C:
Po = ( 1/3, 1/3, 1/3 ) we have to find the distribution of x2 as attached below
after solving the distribution
x 2 = ( 0.4167, 0.25, 0.3333 )
B ) finding the steady state distribution solving

below is the detailed solution and answers
