That is, if 1 i 3, p(i, i + 1) = 0.4, and p(i, i 1) = 0.6, but the endpoints are absorbing states: p(0, 0) = 1 and p(4, 4) = 1 Compute p3 (1, 4) and p3 (1, 0). 1.6. A taxicab driver moves between the airport A and two hotels B and C according to the following rules. If he is at the airport, he will be at one of the two hotels next with equal probability. If at a hotel then he returns to the airport with probability 3/4 and goes to the other hotel with probability 1/4. (a) Find the tran...
