    The probability of choosing Joey first is 1/12.

    If that happens, the probability of choosing Chloe next is 1/11.

    Then, the probability of choosing Zoe after that is 1/10.

    The probability of all these things happening is

    (1/12) x (1/11) x (1/10)

    = 1/1320 = 0.00076 = 0.076 percent
