The random distribution histograms are plotted for the 2D lattice of dimension n (2)  = 500 with (a) p occ(2) = 0.42 and (b) p occ(2) = 0.50. For the 3D lattice, the dimension n(3) = 300 and the occupation probabilities (c) pocc(3) = 0.10 and (d) pocc(3) = 0.14. A Gaussian distribution approximation is depicted in bold, whereas a line following a lognormal distribution is of standard thickness.
