Hi Guys, just need a bit of help with this question. Suppose we have P = [0 1/2 1/2; 1 0 0; 1 0 0] and let Q_0=[x y z] where x,y,z >= 0 and x+y+z = 1.

How would I find Q_(2n) and Q_(2n-1), that is the state distribution after an even or odd number of steps? And then how would we use this to explain whether or not the limit distribution exists.

Thanks in advance :)
