here the question ( and I have two answers please check which one is correct and explain why?

probability to right 2= 0.7 probability to left p = 0.3 probability to reach original point Po = 1 if p = 2 ( 1- 1P-21 if p #2 here P (. 3) + 2 (0-7 ) Po = 1- 10.3-0.7 = 1- 04 Po = 0.6 -> probability to returns to 1 if it stalls from 1!2. Consider the one sided random walk with states 1, 2, - - - . Assume that the Markov chain has a probability of 0.7 of moving one step to the right, and a probability of {1.3 of moving 1 step to the left (Pm = 0.3), nd the probability that the system eventually returns to 1, given that it starts at 1
