Pr is the chemical symbol of the natural chemical element praseodymium.
There is no chemical compound known to me as PG PR.
The chemical symbol of promethium is Pr.
Chemical Property.
Praseodymium, with the chemical symbol Pr, is the chemical element with the atomic number 59.
PR methods include the deliberate and unassisted ways of executing the military PR option.
Suppose there is an event A and the probability of A happening is Pr(A). Then the complementary event is that A does not happen or that "not-A" happens: this is often denoted by A'.Then Pr(A') = 1 - Pr(A).Suppose there is an event A and the probability of A happening is Pr(A).

Given two events, A and B, Pr(A and B) = Pr(A)*Pr(B) if A and B are independent and Pr(A and B) = Pr(A | B)*Pr(B) if they are not.
