Re: simple question about random

Define a routine...

nRandom[n_] := Table[Random[Integer, {0, 10}], {n}]

nRandom[6]
{5, 6, 0, 3, 7, 3}

or...

nRandom[n_] := Array[Random[Integer, {0, 10}] &, n]

nRandom[6]
{5, 8, 3, 4, 2, 5}

or just use on a one time basis...

Table[Random[Integer, {0, 10}], {6}]
{6, 3, 8, 1, 2, 6}

The humble Table command is very useful and much better than For or Do
(which wouldn't even work in this case.)

Hi all... The built-in function "Random" gives a random number in a chosen
range. How can I have, for example, 6 random numbers with a single
instruction? Thank you very much for your answers, and forgive me for the
simple question, but I'm new in Mathematica...
