More interesting might be an approximation, roll two dice and sum the total:

Code:

outcome    roll     probability     desired probability
   0        3           1/18            1/16
   1        5, 6        1/4             1/4
   2        others      7/18            3/8
   3        8, 9        1/4             1/4
   4        11          1/18            1/16

Pauli

That's a very reasonable approximation. I'm sure it'd be acceptable to most engineers.
