# Range & Probability

$$
1\ \leq Green\~Value\_n\leq\ 10+4
$$

The maximum number of Green Value in a building is 14. The maximum number of Green Value that can come from a Common is 10, and when upgrading from a Common's Green Value 10 to a Legendary, the final Green Value is 14.

#### Green Value Probability when Constructed

When building owners proceed with construction, the new building's property factor \[Lay-Bours, Green Value] is determined by the differential probability of the existing building's factor value. The table above (based on the bottom row) shows the probabilities.

{% hint style="info" %}
**If a building is constructed with 2 Green Value** \
→Probability that the Green Value in the new building will be 1 = 66.67%\
→Probability that the Green Value of the new building will be 2 = 33.33%
{% endhint %}

{% hint style="info" %}
**If a building is constructed with 3 Green Value**\
→Probability that the Green Value in the new building will be 1 = 50.00%\
→Probability that the Green Value of the new building will be 2 = 33.33%\
→Probability that the Green Value of the new building will be 2 = 16.67%

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://orbcity.gitbook.io/orbcity/building/green-value-system/range-and-probability.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
