var getRandomLottoNumbers = function (m:Number, n:Number):Array {

m==undefined?m=6:m=m

n==undefined?n=49:n=n

for(var v=[];m;--n)Math.random()*n>m?0:v[--m]=n;return v

}

Using it is quite straightforward. Just pass two arguments to the function - the number of selections you want to make (m), and the total numbers you are selecting from (n). If you omit the arguments, the function will default to selecting 6 random numbers from a total of 49:

// generate 3 random numbers between 1 and 10

trace(getRandomLottoNumbers(3, 10));

// generate 6 random numbers between 1 and 49 (default)

trace(getRandomLottoNumbers());
