Calculating the covariance of two discrete random variables

[QUOTE="Ray Vickson, post: 6028595, member: 330118"] I think your "equi-probable" assumption is the only reasonable interpretation of this poorly-worded problem. If I were doing it I would assume each of the five points has probability 1/5, and I would also add the statement that I was assuming those five points are exhaustive (i.e., that all other points have zero probabilities --- not stated in the problem as you wrote it).
