step 1. Finally, for the first activity ‘Play’, we calculate the backward probabilities for each state: β[Study, 1] = sum(β[Play, 2] * A[s][Study] * B[s][Play]) for all s in states To calculate β[‘Rainy’, 1], we consider both possible next states (‘Rainy’ and ‘Sunny’), and sum over: β[‘Rainy’, 2] *
