BinCounts

Why does BinCounts[] give lists with unpredictable Dimensions[]?

With[{n = 205}, ll = RandomArray[NormalDistribution[0, 1], {n}];
Dimensions[BinCounts[ll, {Min[ll], Max[ll], (Max[ll] - Min[ll])/n}]]]



You may try different values of n (or the same n and different samples of 
the random numbers), and verify that the lenght of the list depends on the 
random realization: somtimes you get n, somtimes n+1.
