HMM, the third state s2 is the only one that can produce the observation y1. Additionally, the only way to end up in state s2 is to first get to state s1. Starting with observations ['y0', 'y0', 'y0'], the most probable sequence of states is simply ['s0', 's0', 's0'] because it’s not likely for the
