This equation can be simplified by replacing the bigram count in the denominator with the unigram count of wn-1. Why do we want to do that?
A. Bigram count can only be normalized by unigram count
B. Sum of all bigram counts that start with the word wn-1 is equal to the unigram count of the same word
C. Normalization using bigram count will make the estimate to be greater than 1 in some cases.
D. None of the above.
