Let X be the average number of dots resulting from two tosses of a fair die. For instance, if the faces 4 and 5 show, the corresponding value of X is (4+5)/2=4.5. Obtain the probability distribution of X and the expected value.

thanks for your time, it's my last problem and i'm stuck!!
 
Since there are only 36 possibilities, I would build the entire distribution and see what it looks like.
