    Knowing the sort of replies you could get on TSR, it would be useful if you tell us what stage you are at. GCSE? S1? S2?

    The clue is given in the question - tree diagram

    Your branches should read 1 and Not 1

    You tried to list out all the possible combinations that would work. That can sometimes be a useful way. In this case it works. You listed 15 combinations working out of a possible 216.

    Therefore the answer is simply ___?

    An alternative method is the tree diagram method, as mentioned by a previous poster. I would advise you to have a read on that on the internet just for future knowledge and to check your answer.

    After you have a read, feel free to come back to this thread and for any queries you may have about that method.
