Let \(A = \{1,2,3,\ldots,n \} \) and \(B = \{1,2,3,\ldots,n\} \). Random numbers \(i\) and \(j\) are chosen from the sets \(A\) and \(B\), respectively. Find the probability of \(i \geq j\). That is, what is \( P(i \geq j) \)?

We have \[n^2\] outcomes and \[n^2+n\over 2\] are good one. So \[P(i\geq j) = {n+1\over 2n}\]
