[Haskell-beginners] Request for Code Review: Dice Game Distribution

[Jan Brusch]

Hi,

I'm currently learning Haskell and as a first project I wrote a little
helper for a dice game. It's very short. Nonetheless I would really
appreciate a little Code Review or any other input.

The Game: Each player writes down the numbers from 1 to 42. Each turn you
roll 3 dice (6-sided). The rolling player can cross of any one number that
he can construct from the three dice using the math operators +, -, *, /.
First player to cross off all numbers wins.

The Helper: Calculates the reachable numbers for each dice roll. It the
aggregates a count for each number, from how many dice rolls it can be
reached. E.g.: There are 216 possible dice rolls (6^3), the number 2 can be
reached form 171 of them. The helper gives out the data in JSON format that
can be read by NVD3 to be displayed in a browser. The graph helps you to
make a decision on which number you should prefer to cross off with your
current roll.

Looking forward to any feedback and thanks in advance
