Solution
In association rule mining, support represents the frequency of co-occurrence of items in transactions. It is a measure of how frequently the items appear together in the dataset. It is calculated as the proportion of transactions in the dataset which contain the itemset. The higher the support, the more frequent the itemset appears together in the dataset.
