Since I did it in the other thread, I figured I'd do it here too.
For anyone interested, on Noble difficulty level (which we're on in this game), these are the probabilities for huts (assuming my files are up to date):
Gold: 35% (large amount 15%, small amount 20%)
Barbarians: 15% (few 10%, lots 5%; ignored if the unit is a Scout)
Free Unit: 15% (warrior 10%, scout 5%)
Map: 10%
Experience: 10%
Tech: 10%
Healing: 5% (ignored if unit is at full health)
That means for a Scout at full health, the probabilities are adjusted to:
Gold: 43.75% (large amount 18.75%, small amount 25%)
Free Unit: 18.75% (warrior 12.5%, scout 6.25%)
Map: 12.5%
Experience: 12.5%
Tech: 12.5%
Remember this only applies for Noble level. These probabilities vary as the difficulty level changes. Generally the higher it is, the less likely you are to get something really nice (like a tech, a free unit, or gold), and the more likely you are to get barbs. In fact the only two things that remain constant across all the difficulty levels from Settler to Deity are that you always have a 5% chance of getting healed if you're damaged, and you always get a 5% chance of getting a Scout. Everything else changes.
