Singlet distribution function generic

This property is not shared by the generic singlet distribution function, and the integral... 

The symbol Pr stands for probability of. ) Relation (2.16) gives the probabilistic meaning of the quantity R ) JR, which is contingent upon the choice of a sufficiently small element of volume JR. The quantity (R ) is often referred to as the generic singlet distribution function. 

As in the case of the singlet MDF, here we also start with the specific pair distribution function defined in (2.28). To get the generic pair distribution function, consider the list of events and their corresponding probabilities in table 2.2. Note that the probabilities of all the events on the left-hand column of table 2.2 are equal.
