b) A Doctor in computer engineering purchases a new computer every two years with preferences for three models; X, Y and Z. If the present model is X, the next computer may be Y with probability 0.2 or Z with probability 0.15. If the present model is Y, the probabilities of switching to X and Z are 0.6 and 0.25 respectively. And if present model is Z then, the probabilities of switching to X and Y are 0.5 and 0.1 respectively. Represent the situation as a Markov chain

b) A Doctor in computer engineering purchases a new computer every two
years with preferences for three models; X, Y and Z. If the present model is
X, the next computer may be Y with probability 0.2 or Z with probability
0.15. If the present model is Y, the probabilities of switching to X and Z are
0.6 and 0.25 respectively. And if present model is Z then, the probabilities
of switching to X and Y are 0.5 and 0.1 respectively.
