Can mobs drop special items?

Solution 1:

Zombies, skeletons and zombie pigmen each have a 2.5% chance of dropping a rare drop, if they drop, there is a 20% chance of it having an enchantment which would cost 5 levels in a enchanting table. Using a sword with the looting enchatement increases these chances.

Skeletons can drop bows, zombies can drop iron tools, helmets or ingots and zombie pigmen drop gold tools, helments or ingots.
