equivalent probabilities
Given a probability space, how do I find the family of all equivalent probabilities on the space?For example,let the discrete random variable X have uniform probability equal to 1/3, taking values 10, 2, and -3. the r.v. is represented on the finite probability space = {1, 2, 3}. How do I find the family of all equivalent probabilties?I am not looking for an outright answer. Hints and a sense of direction would be gretaly appreciated. Assume I am a newbie to math fin
