Q2. Consider a transaction dataset that contains five items, {A, B, C, D, E}. a) Suppose the support of {A, B} is the same as the support of {A, B, C}, which one of the following statements are true or false, and why: [1 point each] 1. Support of {A, B} is the same as support of {A, C}. 2. The confidence of the rule {A, B} - {C} is 100%. 3. The support of {A, B, D} is the same as the support of {B, C, D}. b) Suppose all the transactions that contain {A, B} also contain {B, C}, which one of the following statements are true or false, and why: [point each] 1. The confidence of the rule {A, B} {C} is 100%. 2. The support of {A, B, D} is the same as the support of {B, C, D}. 3. {A, B, D} is not a closed itemset
