Using Cards as Dice (Posted on 2004-08-09) Difficulty: 2 of 5
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?

A card selected twice is not a "pair of cards".  I think the wording clearly implies that one should randomly take TWO cards at one time.

(Or if as you imply, one takes one card at a time, then the wording means without replacement.)
