    Prob = 0.514

    A. independent

    Step-by-step explanation:

    The probability that the club chooses a girl and then a boy for the representative spots

    Total = 15

    Boys = 6

    Girls = 9

    Prob of 2 person, a girl and a boy

    = (9C1*6C1) / (15C2)

    = (9*6) / (105)

    = 54/105

    = 0.514
