apriori association rule query

Hi all,

got a question here... 

I run a dataset using apriopri and set the lowest possible antecedent and consequent at 0 and 5 respectively.

From the results, I notice that the count for all the consequents is the same. for eg 50 for consequent a , consequent b and consequent c. 

Is there a reason for this?

 

Regards

James
