I wanna help with this

Suppose you have two urns with a total of 5 balls. At each step, one of the five balls is chosen at random and switched from its urn to the other urn. Let Xn be the number of balls in the first urn after n switches. i) Is {Xn : n = 1, 2, ...} a Markov Chain? Please explain. ii) Define the state space and provide the one step transition matrix. iii) Draw the corresponding transition graph. iv) Classify the states. Are there any periodic states? v) What is the probability that, given I have 3 balls in the first urn at the 10th turn, I will have 2 balls at the 12th turn
