To simulate rolling a die, we’re going to use the primitive random. Here’s how it works:.
random 6 -→ returns a randomly choosen integer among 0, 1, 2, 3, 4, 5.
Hence, (random 6)+1 returns a randomly choosen integer from 1, 2, 3, 4, 5, 6. We need the parenthesis, otherwise,
the LOGO interpreter should understand random 7. To avoid parenthesis, we can write 1+random 6
too.
We define the primitive called die which simulates rolling one die.
