Loot probability increase

What does the 1.0 mean in the "probability" parameter?  I'm trying to get resources like wood, stone and frag to spawn into the boxes but no matter what I do or how many loot tables I edit they never appear.  I also notice that resources only spawn in TC's.  Can that be changed?

Additional Information

heya,

0.0 to 1.0 is the range where 1.0 is 100% - all items have 1.0 probability by default so it is impossible to spawn them all based on probability. probability is determined once the items are pooled together and selection begins. if you want an item to always spawn then put it in the Base Loot tables and enable Always Spawn Base Loot Table in your profiles.

you can disable by changing Move Resources Into Tool Cupboard

or you can disable specific items from going into tool cupboard by modifying Resources Not Moved To Cupboards
