    (i)
    P(at least one 6)=1-P(no sixes)
    That should be easy enough


    (ii)
    You can identify the combinations possible that give a total of nine or more
    6+3
    6+4
    6+5
    6+6
    (4 combinations)

    5+4
    5+5
    5+6
    (3 combinations)

    4+5
    4+6
    (2 combis)

    3+6
    (1 combi)


    total 5+4+3+1=15 cominbations, all with a probability of 1/36

    Answer: 15/36



    (iii)
    This is the same principle as part II so you should be able to do it now
