# Range & Probability

$$
1\ \leq LayBours\_n\leq\ 10+4
$$

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

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 Lay-Bours** \
→Probability that the Lay-Bours in the new building will be 1 = 66.67%\
→Probability that the Lay-Bours of the new building will be 2 = 33.33%
{% endhint %}

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