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 is a perfect power, while 2*3=6 is not a perfect power)? Express your answer as a common fraction.
