- A 100000 runs of the following code:
_values = [0,1,2,3,4,5,6,7,8,9]; _weights = [0.109,0.65,0.01,1.01,1.24,0,1.59,0.09,1.15,0.55]; _result = _values selectRandomWeighted _weights;Gave this result:0 - 0 0.01 - 144 0.09 - 1409 0.109 - 1633 0.55 - 8673 0.65 - 10127 1.01 - 15668 1.15 - 18059 1.24 - 19518 1.59 - 24769
