quick solution pls

Every year, during the March-through-September growing season, a gardener uses a chemical test to check soil condition. Depending on the outcome of the soil test, productivity for the new season can be one of three states: (1) good, (2) fair, and (3) poor. Over the year, the gardener has observed that last year's soil condition impacts current year's productivity. If this year's soil condition is good, there is a 0.5 chance it will not change next year, and a 0.3 chance it will be fair. If this year's soil condition is fair, there is a 0.5 chance it will not change next year, and a 0.4 chance it will be poor. If this year's soil condition is poor, there is a 0.6 chance it will not change next year, and a 0.3 chance it will fair. a ---- 1.Define the proper states of this system. 2.Construct the set of state space (S = {. } 3.Is this a stochastic system process, and why?. 4.Construct the state transition Diagram for the system. 5.Check (with explaination) for Markovian property (Markov Process)
