Given the following HMM model, where symbols X, Y and Z represent the possible observations in the states. In a circle representing a state, the symbols are equally possible observations in that state. Suppose Tr 1 =1l2, what is the value of P(Q), Q = 818383? ( There are 3 nodes X Y, Z Y, ZX with the following configuration: XY is in state 81 and has a directed edge from X Y to ZY with weight 1/3 ,' there is another directed edge from X Y to ZX with weight 2/3; Z Yis in state 82 and has a directed edge from ZY to ZX with weight 2/3; there is a directed edge from Z Y to X Y with weight 1/3; ZX is in state 83 and there is a self loop at ZX with weight 1/3; there is a directed edge from ZX to Z Y with weight 1/3; there is a directed edge from ZX to X Y with weight 1/3. ) O 1/3
