[This question is in continuation with the previous one.] Which of the following best describes the probability of observation sequence {‘Dry’,’Rain’} given a hidden state ‘Low’ for the observation ‘Dry’?
A. P(‘Dry’ ‘Rain’, ‘Low’ ‘Low’) + P(‘Dry’ ‘Rain’, ‘Low’ ‘High’) + P(‘Dry’ ‘Rain’, ‘High’ ‘Low’) + P(‘Dry’ ‘Rain’, ‘HIgh’ ‘High’)
B. P(‘Dry’ ‘Rain’, ‘Low’ ‘Low’) * P(‘Dry’ ‘Rain’, ‘Low’ ‘High’) * P(‘Dry’ ‘Rain’, ‘High’ ‘Low’) * P(‘Dry’ ‘Rain’, ‘HIgh’ ‘High’)
C. P(‘Dry’ ‘Rain’, ‘Low’ ‘Low’) * P(‘Dry’ ‘Rain’, ‘Low’ ‘High’)
D. P(‘Dry’ ‘Rain’, ‘Low’ ‘Low’) + P(‘Dry’ ‘Rain’, ‘Low’ ‘High’)
Answer:D
