I need to generate 3 random numbers, the amount of which is equal to 1.

My implementation does not support uniform distribution. :(

Answer

Just get 3 random numbers and then calculate a factor which is 1 / [sum of your numbers]. Finally multiply each of the random numbers with that factor. The sum will be 1.
