    The Oakdale High School Speech and Debate Club hosted its annual car wash fundraiser. Each club member brought a bottle of car wash soap, so there were 8 total bottles. 6 of the bottles contained orange soap. If a club member randomly selects 5 bottles to pour into the first soap bucket, what is the probability that all of them contain orange soap?

    This is assumed to be draw without replacement, so we have:
    1. Draw 1: 6/8
    2. Draw 2: 5/7
    3. Draw 3: 4/6
    4. Draw 4: 3/5
    5. Draw 5: 2/4
    Since they are independent events, we multiply:
    6/8 * 5/7 * 4/6 * 3/5 * 2/4
    (6 * 5 * 4 * 3 * 2)/(8 * 7 * 6 * 5 * 4)
    720/6720
    0.1071
