Minecraft wiki entry for Drops, associated text: When killed by a player or a tamed wolf, a monster can drop equipment and armor that it spawned with. Each piece of equipment the monster was spawned with is dropped with an 8.5% chance‌[Java Edition only] or 25% chance‌[Bedrock Edition only],[1] except pumpkins, jack o'lanterns, and vex's iron sword, which have a 0% chance. This value is determined by the mob's HandDropChances and ArmorDropChances tags. The Looting enchantment increases this chance by 1% per level (up to 11.5% with Looting III, and 3% for pumpkins, jack o'lanterns, and said sword)‌[Java Edition only] or 5% per level in some cases‌[Bedrock Edition only]. The chance is rolled for each piece of equipment, so it is possible for a monster to drop more than one piece of equipment upon death.
