Final answer:
The points awarded for owned rollers vary and are determined by the rules established for their context. They can be 2 points, 0.3 points, 5 points, etc., without needing to total 10 points.
Step-by-step explanation:
When assigning points to categories such as owned rollers, it is important to define the point system according to the rules of the game or context in which these rollers are being evaluated. The points awarded for each owned roller can vary; for instance, one could be worth 2 points, another 0.3 points, or even 5 points. It's up to the person or entity in charge of setting up the conditions to decide the value for each roller, and these values do not necessarily need to add up to a total of 10 points.
