A database has six transactions. Let min_sup=65% and min_conf=85%.

(a)List all of the strong association rules (with support s and confidence c) matching the following metarule, where X is a variable representing customers and itemi denotes variables representing items (e.g., A, B, etc.):

(b)Establish the FP-tree and find out Conditional Pattern Base, Conditional FP-tree and Frequent Patterns Generated for item E.
