Text-based stimulus: Transition matrix table with rows Current Green, Current Yellow, Current Red and columns Next Green, Next Yellow, Next Red; sample probabilities shown as Green row 0.80, 0.15, 0.05; Yellow row 0.30, 0.50, 0.20; Red row 0.10, 0.25, 0.65. A device can be in states Green, Yellow, or Red. A transition table gives probabilities for the next state based on the current state. Which implementation is best?
