## Help for a troll definition

 Thu Oct 23 03:29:05 2014   by   Tiziano Contorno Hi all,I can't find a way to do this:Roll Nd6, evaluate probability to get at least C identical dice showing a value greater than R.Example:N = 4C = 3R = 5Roll 4d6, calculate probability to get at least 3 identical dice showing a value greater than 5.Good combinations for this example are:666666616662666366646665Hope this is clear, thank you!Thank you! Thu Oct 23 08:18:14 2014   by   Torben You can do it by first filtering such that only dice greater than or equal to the target number T are retained and then count identical dice.  This is done by first counting Ts, then counting T+1s up to 6s and then taking the maximum of these.  In Troll, this is done like this:`x := 4d6;T := 5;y := T <= x;max (foreach i in T..6 do count i=y)`This will give you the probabilities of getting different numbers of identical dice that meet the threshold.I hope this helps.

Sun Oct 26 12:05:53 2014   by   Torben I just noticed that the definition can be made shorter: You don't need to filter the dice that are less than T, since you only count those that are at least T in the foreach loop.  So you can remove third line and replace y by x in the last line.
