Is there an upper bound for the mean of a ratio between two random variables ?

  • $\begingroup$ Please give substantial setup for your problem, and also add context (why is this problem important or difficult).You will need to know something about the distributions of the two random variables. In particular if there is a positive measure for the denominator to be near zero, then some examples can be given to show the ratio may not have a finite expectation (mean). $\endgroup$ – hardmath Jan 18 at 18:52
