Use what you know: Your take on Diceware

Question

If you're not familiar, Diceware is a method for creating passwords using an ordinary die from a pair of dice as a hardware random number generator.

For the sake of fun, let's ignore anything about the security of computer's random number generators.

Write a function or program that prints or returns a single five-character string containing a random selection of the numbers 1 through 6. These should be chosen with equal probability.

Example valid outputs:

21321
14654
53552
63641

No standard loopholes! This is code-golf, so shortest code in bytes wins.

Answer 1

Dyalog APL, 7 bytes

10⊥?5⍴6

Try it online on TryAPL.

How it works

    5⍴6  Yield (6 6 6 6)
   ?     Roll; turn each 6 into a random integer between 1 and 6.
10⊥      Decode with base 10.

Answer 2

Julia, 24 bytes

print(join(rand(1:6,5)))

We use rand to get an array of length five consisting of elements randomly chosen from the range 1:6. We join it into a string using join then print it to STDOUT using print.

a.{~49+?5$6

Explanation:

        5$6    NB. repeat 6 five times      output: 6 6 6 6 6
       ?5$6    NB. 5 random integers < 6    output: 4 5 1 0 2
    49+?5$6    NB. add 49 ('1') to them     output: 53 54 50 49 51
a.{~49+?5$6    NB. convert them to ASCII    output: 56213

Answer 8

MATLAB / Octave, 12 bytes

[49+6*rand(1,6),'']
ans = 153361

rand(x,y) creates a random array with dimensions (x-by-y) with numbers between 0 and 1. Multiply this by 6 to get values between 0 and 6. Add 49 to get a value 49 < n < 55 (the random number will never be exactly 0 or 1). [...,''] converts this to strings with the floored values of n (integers [49 54] corresponding to [1 6] in ASCII.
