3. Suppose there are 100 items, numbered 1 to 100, and also 100 baskets, also numbered 1 to 100. Item i is in basket b if and only if i divides b with no remainder. Thus, item 1 is in all the baskets, item 2 is in all fifty of the even-numbered baskets, and so on. Basket 12 consists of items (1, 2, 3, 4, 6, 12), since these are all the integers that divide 12. Answer the following questions: (a) If the support threshold is 5, which items are frequent? (b) what is the confidence of the following association rules? (1) (5, 7) 2. (2) (2, 3, 4)+5.
