Analyzing Conflicting Model Predictions
Based on the provided information, determine which word the model will select for two different values of the blending coefficient: a) λ = 0.2 and b) λ = 0.8. Justify your answer for each case by showing the final probability calculation for both words.

A language model combines a base probability distribution, P_lm, with a retrieval-based distribution, P_knn, to predict the next token. The final probability is calculated by blending these two distributions using an interpolation coefficient, λ = 0.6. Given the distributions below for a small vocabulary, which token will the model select as its final output?
- P_lm: {'wordA': 0.5, 'wordB': 0.4, 'wordC': 0.1}
- P_knn: {'wordA': 0.2, 'wordB': 0.7, 'wordC': 0.1}
