The numbers from 1 to 150, inclusive, are placed in a bag and a number is randomly selected from the bag. What is the probability it is not a perfect power (integers that can be expressed as \(x^y\) where \(x\) is an integer and \(y\) is an integer greater than 1. For example,\(2^4=16\)  is a perfect power, while \(2*3=6\) is not a perfect power)? Express your answer as a common fraction.
