Suppose we train a trigram language model with add-one smoothing on

Suppose we train a trigram language model with add-one smoothing on a given corpus. The corpus contains V word types. Express a formula for esti- mating P(w3|w1,w2), where w3 is a word which follows the bigram (wl,w2), in terms of various N-gram counts and V. Use the notation c(wl,w2,w3) to denote the number of times that trigram (wl,w2,w3) occurs in the corpus, and so on for bigrams and unigrams
