+# ProbabilityCollection
+
+A Probability Collection is a representation of a weighted pool.
+
+Example:
+* `a` has a 1/5 (20%) chance, `b` and `c` both have a 2/5 (40%) chance.
+  ```yml
+  - a: 1
+  - b: 2
+  - c: 2 
+  ```
+
+# Weighted Pool
+
+A weighted pool is a way to randomly select one of many objects from a "pool" based on "weight".
+
+## Pools
+A pool is a list of objects from which selections will be pulled.
+
+## Weight
+Weight is the *relative* probability that any object will be selected from the pool. Each object in the pool has a
+weight, meaning the chance of object O being selected from pool P is `weight(O)/sum(weight(P_n))`.
+
+## Example
+Here's an example pool:
+```yaml
+OPTION_A: 2
+OPTION_B: 1
+OPTION_C: 1
+```
+In this YAML-based pool, the keys are the objects, and the values are the weights. If we want the probability that
+`OPTION_A` will be selected, we sum all weights, and divide the weight of `OPTION_A` by that sum.  
+`2 + 1 + 1 = 4`   
+Therefore the probability that OPTION_A will be selected is `2/4`, or 50%.
+
+## Manipulating weights to get a desired probability
+What if we want Option A to have a 60% chance of being selected? This requires manipulating the weights of all objects
+in the pool, since with B and C having a weight of 1, there is no integer weight that can be assigned to A that will
+give it a probability of 60%. What is usually done is that the weights are given a set sum that is easy to work with.
+Usually this is 100, since with a sum of 100, every object's weight is equal to the percent chance it will be selected.
+By applying this to the above example, we can produce this pool that has a 60% chance of A being selected:
+```yaml
+OPTION_A: 60
+OPTION_B: 20
+OPTION_C: 20
+```
+
+## Use Cases
+Sometimes, it is undesirable to have an equal probability of all objects being selected, so you may want to "weight"
+some objects higher, so they are selected more often.
