Every pack, every rarity.
A grid view to compare how different packs shift their probability mass across rarities.
Every pack opens as an independent event.
Blooket pack openings are a categorical random variable: each pack rolls once, and the probability of each rarity is fixed. Expected drops across N packs is simply rate × N. The full derivation, including why expected value undersells the variance, lives in drop rates explained.
For chase questions (Rainbow Panda, King of Hearts, etc.) switch to the chance calculator and its 50 / 90 threshold widget instead; cumulative probability and expected value answer different questions. Both tools are part of the broader blooket calculator.
