Z = the sales tax percentage for a randomly selected amazon purchase, where n = the total number of possible sales tax percentages for online purchases

It cannot exceed the tax percentage for online purchases that can be found in Amazon. $Z_n$ is a set of online purchases that can be found on Amazon, therefore the set of possible values for the variable is $[0,Z_n]$
