Why is there a +2 in the denominator of the last formula of the video…Why isnt it +1

hey @aarushi26 ,
In multivariate bernoulli naive bayes we consider 1/0 for each word which means we take 1 if word is present and 0 if word is not present. So for every word has two choices only, and while applying laplace smoothing we add 1 to the numerator, and 2 to the denominator.
i hope this helps.
Happy Leaning
