The variables \(x\), \(y\), and \(z\) are selected independently and uniformly from the five-element set \(\{p,q,r,s,t\}\). A relation \(R(x,y,z)\) is false exactly when \(x\), \(y\), and \(z\) are the three distinct elements \(q\), \(r\), and \(s\), in any order. Let \(P_R\) denote the probability that \(R(x,y,z)\) is true. Which statement is correct?
