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
A potato can be on farmland to plant a potatoes crop. When farmed, potatoes require 8 stages to grow. However, there are only 4 distinct textures, so only 4 visible stages: every two stages have the same texture, except that growth stage 7 keeps the same appearance as stages 5 and 6, so that only stage 8 has the final, 'mature' appearance.

Fully grown potato crops drop 1 to 4 potatoes (about $2 5/7$ per crop harvested on average) and have a 2% chance of dropping an additional poisonous potato. Potato yield can be increased using a tool enchanted with fortune. Bone meal can be used to mature the potato to its last stage of growth.
