To classify the class (Species) of X = {Color=Green, Legs=2, Height=Tall, Smelly=No} using Naive Bayes, we first calculate prior probabilities and likelihoods from the given dataset. Step 1: Calculate Prior Probabilities * Total records = 7 * Number of M = 4 → P(M) = 4/7 * Number of H = 3 → P(H) = 3/7
