support calculation formulas

Support calculation in the context of general knowledge typically refers to determining how often a particular item, event, or piece of information occurs within a dataset. The formula for support is: **Support(A) = (Number of occurrences of item A) / (Total number of items in the dataset)**. This formula helps assess the importance or relevance of item A within the entire set. For instance, if you have a list of 100 books and 10 are mystery novels, the support for mystery novels would be 10/100, or 0.1, indicating they make up 10% of your total collection.
