No, they are found in nature from natural resources and not made by humans and not chemically changed as much.
Define trade.
The exchange of goods AND ideas (services).
What do outcomes mean in math?
All the possible results that can happen.
Why does trade occur?
Sharing ideas, goods and services, economic greed, cosmetic reasons
What are natural resources?

What are some examples of trade?
Trading goods: Clothes, resources, etc.
Trading ideas: Music, technology, religion, etc.
What does theoretical probability mean?
What is expected to happen for an event based on math.
Does trade have a economic or creative/cosmetic purpose or both? Why?
Both! It drives growth and lower prices and it faciliates cultural exchange and the spread of goods and services.
