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 baskets, item 2 is in all fifty of the even-numbered baskets, and so on. Basket 12 consists of the items {1, 2, 3, 4, 6, 12} since these are the integers that divide 12. Answer the fol- lowing questions: (a) If the support threshold is 5, which items are frequent? (b) If the support threshold is 5 which pairs of items containing item 20 are frequent? (C) For a support threshold of 5, give three different frequent triples con- taining item 5. For each of your frequent triple, list 5 baskets where the different items appear together.
