Potato

Potatoes are food items that can be planted, consumed raw, or cooked in a furnace or a campfire to make baked potatoes.

Zombies
Zombies, husks, and zombie villagers have a 2.5% chance of dropping either an iron ingot, carrot, or potato when killed by a player or tamed wolf. This is increased by 1% per level of looting. This gives potatoes the following chances of dropping:
 * $1/120$ (about 0.83%)
 * $11/600$ (about 1.83%) with Looting I
 * $17/600$ (about 2.83%) with Looting II
 * $23/600$ (about 3.83%) with Looting III

Farming
Fully grown potatoes crops drop 1 to 4 potatoes (about $2 5/7$ per crop harvested on average). Using a tool enchanted with fortune increases the maximum number of potatoes dropped by 1 per level. Immature potato crops drop one potato when broken. A potato can be on farmland to plant a potatoes crop.
