The figure above presents two HMMs$.$ States are represented by circles and transitions by edges. In both, emissions are deterministic and listed inside the states. Transition probabilities and starting probabilities are listed next to the relevant edges. For example, in HMM $1$ we have a probability of $0\mathrm{.}5$ to start with the state that emits A and a probability of $0\mathrm{.}5$ to transition to the state that emits B if we are now in the state that emits A$.$
