The normal distribution is a bell-shaped curve where data clusters symmetrically around the mean, useful in statistics and natural phenomena modeling.
These properties imply that there is no pattern to a table of random digits. Information about some of the table will not help at all to determine the other entries of the table. For example, the following string of digits would be a sample of a part of a table of random digits: ...
