Independence in combinatorial scenarios

A question is this type if and only if it involves testing independence of events defined by combinatorial outcomes (e.g., marble arrangements in boxes, specific dice configurations).

5 Marco has four boxes labelled \(K , L , M\) and \(N\). He places them in a straight line in the order \(K , L , M\), \(N\) with \(K\) on the left. Marco also has four coloured marbles: one is red, one is green, one is white and one is yellow. He places a single marble in each box, at random. Events \(A\) and \(B\) are defined as follows.
\(A\) : The white marble is in either box \(L\) or box \(M\).
\(B\) : The red marble is to the left of both the green marble and the yellow marble.
Determine whether or not events \(A\) and \(B\) are independent.
