A hat contains tickets marked 1, 2, ..., n. A ticket is drawn from the hat, and then, without the first ticket being replaced, a second ticket is drawn from the hat. What is the probability that the first ticket drawn is the number 1 and the second ticket drawn is the number 3?
(A) \(\ \ \frac{1}{n}\)
(B) \(\ \ \frac{1}{n-1}\)
(C) \(\ \ \frac{1}{n^2 -n}\)
(D) \(\ \ \frac{2n-1}{n^2-n}\)
(E) \(\ \ \frac{1}{n^2}\)
