Step-by-Step Solution
Solution:
Step 1: Understand unigram model calculation
Unigram model assumes words are independent, so multiply their probabilities.Step 2: Calculate sentence probability
Multiply P(I) * P(love) * P(AI) = 0.2 * 0.1 * 0.05 = 0.001Final Answer:
0.001 -> Option BQuick Check:
Unigram multiply all word probs = 0.001 [OK]
Quick Trick: Multiply all word probabilities for unigram [OK]
Common Mistakes:
MISTAKES- Adding probabilities instead of multiplying
- Using conditional probabilities (bigram) by mistake
- Incorrect multiplication order
