LEASE JUST GIVE THE OPTIONS! 1- Choose all of the following which is true about confidence of association rules Select one or more: a. Confidence is used to quantify strength of a rule b. Confidence is defined as confidence(A -> B) = P(BIA), = P(A) + P(B) c. Contidence is detined as the probabilitv that B occurs when A occurs d. Contidence is defined as the probability that either A or B occurs e. It is a common practice to favor rules whose confidence is above a threshold value 2- Choose all of the following which is true about the "lift" of association rules Select one or more: a. Lift is an indicator of the strength of an association rule b. Lift is only used to filter unimportant events c lift and support can be used as alternative measures for the same purnose d. Lift and confidence can be used as alternative measures for the same purDose e. Lift is the probability of A and B occurring together divided by their joint probability if they were they were independent events
