can someone please help me understand this?? I am confused...

I Is the transition matrix for a 4- state absorbing Markov Chain . State # 1 and state # 2 are absorbing states . T = O 1 O O 0. 15 0. 35 0. 5 . O . 2 O 0. 5 0 . 3 Use the standard methods for absorbing Markov Chains to find the matrices N = ( I - Q )' and B = NR. Answer the following questions based on these matrices . ( Give your answers correct to 2 decimal places . ) ( a ) If you start in state # 3 , what is the expected number of steps needed to reach an absorbing state . ( Your answer will come from the matrix N. ) ( NO Response )\\ steps ( b ) If you start in state # 4 , what is the expected number of steps needed to reach an absorbing state . ( Your answer here will come from the matrix N. ) ( NO Response \\ steps ( C ) If you start in state # 3 , what is the probability that you will eventually land in state # 1 ? ( Your answer will come from the matrix B. ) ( NO Response )\\ ( d ) If you start in state # 4 , what is the probability that you will eventually land in state # 1 ? ( Your answer will come from the matrix B . ) ( NO Response )
