The package Statistics`NormalDistribution` has the cumulative
(CDF) of a normal sidtribution (and the package 
Statistics`ContinuousDistributions` covers quite a few other 
distributions)


In[2]:=
Needs["Statistics`NormalDistribution`"]

In[3]:=
CDF[NormalDistribution[mu, sigma], x]

Out[3]=
1/2*(1 + Erf[(-mu + x)/(Sqrt[2]*sigma)])
