    Hello, soccerchic96!

    It's kind of simple, isn't it?


    Which is greater, the probability of choosing a number divisible by 6
    or the probability of not choosing a number divisible by 8?
    (numbers 1-50)
    We have 50 numbers to choose from.

    How many are divisible by 6?
    . . Eight of them: 6, 12, 18, 24, 39, 36, 42, 48
    . . Hence: . P(\text{div. by 6}) \:=\:\frac{8}{50}

    How many are divisible by 8?
    . . Six of them: 8, 16, 24, 32, 40, 48
    So there are forty-four which are not divisible by 8.
    . . Hence: . P(\text{not div. by 8}) \:=\:\frac{44}{50}

    Now which is greater?
