    How can i draw a tree diagram to show this data...
    In a gambling game, players pay 1 entry fee. They then throw a die untill it shows a six. If only one throw is needed the player recieved 3. if two throws are needed, the player recieves 2. If three throws are needed, the player gets his her entry fee back, otherwise 1 is lost.

    How can i show from a probobility tree,
    the probobility that a player gets;
    1) 3
    2)2
    3)Gets the 1 entry fee back
    4)looses the money

    Probability of getting a 6 is 1/6
    Probability of not getting a 6 is 5/6

    First two branches show the first throw, so the top branch shows getting a 6 on the first throw, with probability 1/6 and winning 3.
