1. Let X and Y be jointly\"r discrete random variables [you could think of X as being the return of some stock and Y be the return of another stock}. Their joint probability distribution is described by the following table 3:4 3:2 y=9 y=4 Answer each of the following questions [and show all the steps required to arrive at the solution.
