Mathematical Discussion

I've done a little math; and here's my results.

Question: "If you see a booster box, and someone takes N packs, and you buy a pack, what are the chances that you will get a ultra rare card?"

So, there are 24 packs in a booster box. For this example, let's say someone takes 1 pack. Now, the chances of getting a Ultra Rare are 1/12, so, the chance that the pack he/she took as a Ultra Rare is 1/12, and the chance that the pack he/she took doesn't have an Ultra Rare is 11/12.

Now, if the pack he took had an Ultra rare, then, assuming that the 1/12 probability is in place, there is 1 Ultra Rare left, and 22 packs without Ultra Rares. Thus, if you choose a pack in this scenario, the chance that it will have an Ultra Rare are 1/23.

If the pack he took DIDN'T have an Ultra Rare, then, assuming that the 1/12 probability is in place, there are 2 Ultra Rares left, and 21 packs without Ultra Rares. Thus, if you choose a pack in THIS scenario, the chance that it will have an ultra rare are 2/23.

Well, the 1/23 scenario only happens 1/12 of the time, so the chance that you pick up a pack with an Ultra Rare when the missing pack had an Ultra Rare is 1/276.

Likewise, the 2/23 scenario happens 11/12 of the time, so the chance that you pick up a pack with an Ultra rare when the missing pack did not have an Ultra rare is 22/276.

If you add 22/276 and 1/276 up, you get 23/276, which --- DUN DUN DUN! --- can be reduced to 1/12.

If you do it with 2 packs, you'll have the instance of both Ultra Rares being taken, but even so, you'll get 1/12.

So; it DOESN'T MATTER which pack you choose, how many are left when you choose it, or when you choose it; it has the same probability.

Thank You.

Asian English cards

I have a quick question about Asian-English Yu-Gi-Oh! cards. I'm going to Japan the day after tomorrow, and I want to buy some cards there. I know they print English cards and distribute them in Japan, but after looking at some of the newer booster packs, there doesn't seem to be any Asian-English varieties for those packs. From what I can tell, they stopped printing Asian English cards after Enemy of Justice... is this true? 75.3.93.95 03:41, March 24, 2010 (UTC)

Ultimate and Ghost rare odds in the TCG

Shouldn't this include the odds of getting an Ultimate or Ghost rare card in TCG booster packs? Lugia61617 (talk • contribs) 11:57, June 19, 2011 (UTC)

AFAIK, there are no such officially documented odds, and any fan-based speculation doesn't use a sufficiently large sample size to end up with accurate figures. Correct me if I'm wrong, though (with references). 「ダイノガイ千？！」^{? · ☎ Dinoguy1000} 12:26, June 19, 2011 (UTC)

More Rares

I found something interesting in all Boosters (TCG) from Duelist Genesis onwards, like if you get a Super rare or above you still get a rare, but the number of commons decreases to seven, do you think we should mention this little tidbit, also with reissued boosters i have found this common, like Samurai Assault's Strike of Neos--LeafGreen Ranger (talk • contribs) 06:22, January 24, 2012 (UTC)

The number of cards per pack.

I am a complete newbie and comes here after checking some booster packs on this site: http://www.yugioh-card.com/en/products/bp-redu.html. All packs I checked say they have 100 each. And now I am a bit confused. I don't think TCG cards would be that cheap in price and... Am I mistaking something? —This unsigned comment was made by 113.190.177.156 (talk • contribs) 19:36, September 8, 2012

Unfortunately, there's a bit of confused terminology going on here: "Booster Pack" refers to the entire set, whereas "pack" refers to the individual package you usually get cards from a Booster Pack in. This is why the Yugioh-Card.com site says Booster Packs have 100 cards each: it's referring to the entire set, instead of per-pack. 「ディノ奴千？！」^{? · ☎ Dinoguy1000} 20:09, September 8, 2012 (UTC)

I see. Thank you very much for the kind explanation. 113.190.177.156 (talk) 20:49, September 8, 2012 (UTC)
