    here is what i made:

    (5!*3!)/(2!*2!*3!)=30
    (3!*3!*2!*2!)/(3!*2!*2!)=6
    30-6=24

    The answer should be 18
    still i don't get the correct answer

    this question is very easy if you do not use a complicated formula
    Treat the 3 yellows as one lump and write down an organized attempt
