Dear amit below I reply to both of your questions
appeared to the forum.


Amit you did a very common mistake for beginners

You use the ( ' ) key  instead of the correct (`) key!

Try the following command and everything is ok.

<< Statistics`NormalDistribution`

That is the two singles quotes used here are "back quotes"
usually found on the same key with ~.
They are NOT the single quotes found on the double-quote key.

Note that the back-quote character is used to separate the package
from the directory name, and at the end in place of .m.

See the following link for more information.

Following also one of the invaluable suggestions of David Park
I recomend you to use the following command in order to load the


In this way you avoid conflicts of possible reloading of the package.




n = 100; A = RandomArray[NormalDistribution[], {n, n}];

Short[A, 10]
