When you open a pack of trading cards, you’re essentially participating in a chance-based event. Odds describe the likelihood of pulling a specific card or set of cards from that pack. In the context of trading card packs, odds are typically represented as a ratio (e.g., 1:10) or a percentage (e.g., 10%). Here’s how it works:

1. Per Pack Basis

• Odds are independent for each pack. This means that every time you open a pack, the odds of getting a specific card are the same, regardless of how many packs you’ve already opened. For example, if a pack has a 1:10 chance of containing a rare card, each pack you open has a 10% chance of giving you that card.

2. Understanding the Ratio

• 1:10 Odds: This means you have a 1 in 10 chance (10%) of pulling that specific card in any given pack.
• 1:100 Odds: In this case, the chances are much lower—there's a 1 in 100 chance (1%) of getting the card you're hoping for in a single pack.

3. Not Cumulative

• The odds don’t "stack" across multiple packs. If you're hoping to get a rare card with 1:10 odds, your chance of getting that card is the same in the first pack you open as it is in the 10th pack. There’s no guarantee that you’ll pull the card after a certain number of packs.

4. How Pack Odds Are Determined

• Rarity: The rarer a card is, the harder it is to pull. Cards with higher rarity usually have lower odds (e.g., 1:100) compared to common cards (e.g., 1:2).
• Product Type: Some packs may had a different cost value because they offer better odds or contain more cards, increasing your chances of getting a rare collectible.
• Special Editions: Certain special packs may feature promotional odds, where the chance of getting a rare card or exclusive collectible is higher but may come with a different cost. 

5. Guaranteed vs. Random

• Some trading card packs offer a guaranteed card, meaning that certain high-rarity cards will be in the pack, but the odds for other rare or special cards may still be randomized.
• Other packs may be entirely random without any guarantees, making the odds for certain cards entirely based on chance.

Example:

Let’s say a pack of cards has a 1:10 chance of containing a rare "Gold" card and a 1:50 chance of containing a legendary "Diamond" card. This means:

• Every pack you open has a 10% chance of containing the "Gold" card.
• The "Diamond" card has a much lower 2% chance of being included in any given pack.

But remember, just because the odds say 1:10 doesn’t mean you’ll get that rare card in your first, second, or even tenth pack—it’s all based on probability.

Conclusion:

Understanding odds in pack opening is key to managing your expectations and enjoying the thrill of collecting. While some cards may be easier to obtain, others may take more time and packs to acquire, so it’s important to know your odds and enjoy the process!
