In the game of Ludo, a player has to throw one die and move a selected token based on the number shown on the die. If a six is shown, the player takes an additional turn in the same round and the number of moves is the number shown the second time and the previous six. If a six appears for the second time, the process is repeated with the move depending on the number shown and the previous throws. If a six appears for the third time, the turn of the player ends without moving the token. Determine the sample space of one such throw and determine the probability for each event.
