Q2: Compute the transition matrix to the 1000th power in maple
A2:

P := [[0.4, 0.5, 0.1], [0.2, 0.7, 0.1], [0.6, 0.3, 0.1]]:

evalm(P^1000);
           [0.3000000000  0.6000000000  0.1000000000]
           [                                        ]
           [0.3000000000  0.6000000000  0.1000000000]
           [                                        ]
