In a laboratory experiment, two mice will be placed in a simple maze with one decision point where a mouse can turn either left (L) or right (R). When the first mouse arrives at the decision point, the direction it chooses is recorded. Then, the process is repeated for the second mouse. The tree diagram should be drawn where the first stage represents the decision made by the first mouse and the second stage represents the decision made by the second mouse.

Determine all four possible decision outcomes for the two mice.
