Given a positive integer \(n > 1\). Let \(a_{1}, a_{2}, \cdots, a_{n}\) be a permutation of \(1, 2, \cdots, n\). If \(i < j\) and \(a_{i} < a_{j}\), then \(\left(a_{i}, a_{j}\right)\) is called an ascending pair. \(X\) is the number of ascending pairs in \(a_{1}, a_{2}, \cdots, a_{n}\). Find \(E(X)\).
