You have probably overlooked the fact that the add-on package Graphics`Graphics` (where Histogram resides) has to be loaded prior to using any function contained in it. Here is the complete code that will do what you want:

In[1]:=
<<Statistics`ContinuousDistributions`
In[2]:=
normdata=RandomArray[NormalDistribution[0,1],100];
In[3]:=
<<Graphics`Graphics`
In[4]:=
Histogram[normdata]


It works without a hitch.
Caveat: If you forget to launch the package and try to evaluate Histogram (with no results, of course), for example, you must Remove[Histogram] before loading the package. The same goes for any function in any package.

Hello..
i am quite new to mathematica...
i am trying to plot a histogram of some data..
i have a list x filled with values, when i type 
normdata = RandomArray[NormalDistribution[], 100];
Histogram[normdata]
it responds with nothing (these 2 lines are taken from the examples).
i can't see what's wrong..
could you please help me?
thank you...
urs..
