If you are using version 6, you can generate a single normal deviate using RandomReal[NormalDistribution[0, 1]] or an array of n normal deviates using RandomReal[NormalDistribution[0, 1], n] In these examples, I've assumed a zero mean and unity standard deviation. Look up NormalDistribution and RandomReal for more details. If you are using an earlier version of Mathematica, first do: <<Statistics` then Random[NormalDistribution[0, 1]] will generate a single normal deviate and Table[Random[NormalDistribution[0, 1]],{n}] will create an array of n normal deviates -- To reply via email subtract one hundred and four
