What are the chances of getting a rare pokemon card in a booster?

The chances of obtaining a rare Pokémon card in a booster pack can vary significantly depending on the set and the specific card rarity. Generally, standard booster packs contain a mix of common, uncommon, and rare cards, with rare cards typically appearing at a rate of about 1 in 5 packs. However, ultra-rare or secret rare cards are much harder to find, often appearing in 1 in 20 packs or less. Therefore, while it's possible to get a rare card, the odds can be quite low depending on the specific card and set.
