medium📝 Predict Output Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Identify the trigram probability for 'sunny'
The probability needed is P('sunny'|'the', 'very') = 0.2.Step 2: Calculate sentence probability
Assuming start tokens have probability 1, the sentence probability equals 0.2.Final Answer:
0.2 -> Option DQuick Check:
Trigram sentence probability = 0.2 [OK]
Quick Trick: Use trigram probability for last word given two previous [OK]
Common Mistakes:
