The first one (where you multiply by 6 and add 1) will give you a number from 1 to 6.

The second one (multiply by 7) will give you a number between 0 and 6.

Both include 6, and you didn't mention what this might be used for; but if you're trying to emulate rolling dice, the first one would be the correct formula.
