  Their sum and a default bucket offset (called *weight_4* in *Figure 13*) forms the *Exposure Score*. 
 Finally, the maximum of the *total risk score* over all the considered events, i.e. the largest risk score, is normalized and then multiplied with the above exposure score. The resulting product of the *exposure score* and the *normalized maximum total risk score* then forms the so called **combined risk score**.
 
-The combined risk score is used to determine which defined risk level should be displayed to the user, e.g. “low risk” or “high risk”. For this decision, [app-defined thresholds](https://github.com/corona-warn-app/cwa-server/blob/eb8be6c3e9c723c62c619784e41889d10054cc93/services/distribution/src/main/resources/master-config/risk-score-classification.yaml) for the individual risk levels apply.

 As the values above are multiplied with each other, a single category with a risk score of 0 means that the overall risk score is also 0. 
 Additionally, a central threshold for the combined risk score specifies whether an exposure event should be considered or not. 
 Furthermore the Google/Apple framework allows to set a [```minimalRiskScore```](https://developer.apple.com/documentation/exposurenotification/enexposureconfiguration/3583692-minimumriskscore) to exclude exposure incidents with scores lower than the value of this property.
