PLEASE I HAVE A SIMPLE QUESTION

WELL I AM BRAND NEW TO MATHEMATICA. THEN I STILL EXPERIENCE SOME DIFICULTY TO DEAL WITH THIS LANGUAGE AND I CANT FIND SOME more SIMPLE NOTATIONS.

FOR THE MOMENT I NEED TO PICK A RANDOM SAMPLING OF “4” NUMBERS FROM A SET " t " OF PREVIOUSLY SELECTED NUMBERS , FOR “n” TIMES.

EXAMPLE t = { 1,4, 6,27, 34, 56,78,82, 100, 123,222, 232…} THEN OUPUT FOR 2 TIMES { 4,27 ,222,56}; { 1,34, 56,123} -- AND SO ON.

THANKS A LOTS IF SOMEONE AT MORE ADVANCED LEVEL COULD SOLVE A SUCH SIMPLE QUESTION,. THIS IS FOR A PROJECT OF ANALYTICAL CHEMISTRY.

Dear Andre,

I am not sure whether I understand what you want but it is similar to what this does?

```auto
t = {1, 4, 6, 27, 34, 56, 78, 82, 100, 123, 222, 232}

Table[RandomChoice[t, 4], {k, 1, 5}]

```

Cheers,  
M.

Typing your question in all caps pretty much guarantees that most people who might otherwise consider answering won’t even read the title.
