A Markov chain X0, X1, X2 ... on states 0, 1, 2 has the transition probability matrix
0 1 2
0 0.3 0.2 0.5
P = 1 0.5 0.1 0.4
2 0.5 0.2 0.3
and initial distribution p0 = P(X0 = 0) = 0.2, p1 = P(X0 = 1) = 0.3, and p2 = P(X0 = 2) = 0.5. Determine the following probabilities:
(1) P(X0 = 1, X1 = 1, X2 = 0);
(2) P(X1 = 1, X2 = 2 | X0 = 2);
(3) P(X3 = 0, X4 = 0, X5 = 2 | X2 = 1);
