Weight = spawn weight of the mob in its category · Chance = weight ÷ total weight of the category · Group size = how many spawn together.
In Java Edition 13 mob types can spawn in Ice Caves — hostile mobs: Creeper, Slime, Spider, Skeleton, Zombie and Frostbite and 4 more; passive mobs: Glow Squid; ambient mobs: Bat.
Creeper, Slime and Spider share the highest spawn weight among the hostile mobs: 100 of 520 (19.2% each) in Java Edition.
Yes. Java Edition lists 12 spawn entries for Ice Caves, Bedrock Edition 13. For example, Creeper has a weight of 100/520 (19.2%) in Java and 100/570 (17.5%) in Bedrock. Use the edition switch above the tables to compare.
Each spawn attempt first picks a category (for example hostile or passive mobs), then one mob of that category at random, weighted by its spawn weight. A mob's chance is its weight divided by the total weight of its category in the biome — so the shares in each table add up to 100%.
