Use BinomialDistribution (which is in Statistics`DiscreteDistributions`) to 
generate the data, and use Histgram (which is in Graphics`Graphics`) to plot 
the data.

Here is an example of how to do this:

<<Graphics`Graphics`
<<Statistics`DiscreteDistributions`
bdist = BinomialDistribution[34, 0.3];
bdistdata=RandomArray[bdist,100];
Histogram[bdistdata];
