[Jprogramming] Dice rolls

[David Vaughan]

Thanks.

Before you sent that, I was messing around with the power conjunction and came up with:

   d1=. 1 2 3 4 5 6
   (+/%#)7=,d1(+/)^:1 d1
0.166667

Set n in ^:n to rolls-1.

Which method, yours or mine do you think is the better one for speed and space?
