A deck of nine cards can be numbered, so that the sum of the numbers on a randomly chosen pair of cards totals to an integer from 2 to 12 with the same frequency as rolling two standard dice. What are the numbers on the nine cards?
The required numbers (in increasing orders of magnitude) are:
0.5, 1.5, 2.5, 2.5, 3.5, 4.5, 4.5, 5.5, 6.5
