Eight rooks are placed randomly on different squares of a chessboard. If the probability that none of the rooks is under attack by another rook can be expressed as \(\dfrac{A}{B}\) for positive coprime integers \(A,B\), then find the value of \(A+B\).

**Note:** You may use a **Calculator** at the last step of your solution.
