How to calculate the expected value?

EV =  Pr(x)*vr(x)+[1-Pr(x)]*vnr(x)
 
Pr(x) := probability for feature vector x to belong to class r
 
1-Pr(x) := probability for feature vector x to not belong to class r
 
vr(x) := value for the business, if feature vector x belongs to class r
 
vnr(x) := value for the business, if feature vector x belongs not to class are
