Histogram gives the plot, but if you want the actual bin counts, use 
BinCounts. The mma help will give you the options to call it; I usually use

BinCounts[data,dx] in which dx is the bin width. You can also specify 
all the bins with BinCounts[data,{xmin,xmax,dx}]. It is then easy to 
convert the counts to probability densities.
