En provenance du site de Victor...
Hi all,
I happened to see that someone had posted statistics from a multimillion spins investigation on "another" board.
Because I like you people here so much, I post these tables so that you don't have to do the same kind of boring and time-consuming tests again, just because your amount of spins isn't 12M...
And NO; I didn't run some thousands of billions of spins to get to these figures: [b]I used my calculator[/b] ;D
Very simple.
[i]Please [b]compare[/b] these figures to tests that you have seen or done![/i]
(The "50/50" values are true 50% chance - like coin-tossing)

If you've got a calculator... WHY spend time doing boring multimillion spins tests?
The end results are the same... Aren't they?

Qui est ce Victor qui a l'air d'avoir un site bien connu ??
J'ai cherché mais je n'ai pas trouvé .
Merci .

Merci,
j'avais déjà mis ce forum dans mes favoris et n'avais pas fait le lien avec Victor.
Très intéressant.
Comme je me débrouille assez bien en Anglais, j'arrive à comprendre.
Par contre, les forums allemands, c'est plus compliqué
