Imagine that documents are drawn from a number of classes of documents which can be modélled as sets of words where the (independent) probability that the i-th word of a given document occurs in a document from class C can be written as

(For this tréatment, we simplify things further by assuming that the probability of a word in a document is independent of the length of a document, or that all documents are of the same length).

Now, by their definition, (see Probability axiom)
