```It is the simplest solution, I think--if you really want to use RandomArray. For most distributions, it probably isn't worthwhile, but it is for the continuous uniform distribution, because Random[] has problems with randomness. RandomArray does better, I think, according to a post I recall from a few weeks ago.

Normal variates are generated in pairs, too, and Random[dist] throws one of them of them away, if dist is normal.
