    A study consists of randomly selecting 14 newborn babies and counting the number of girls. If we assume that boys and girls are equally likely and if we let x=number of girls among 14 babies, then x is a random variable because its values depends on chance. The possible values of x are 0,1,2,...,14. The Below table lists the values of x along with the corresponding probabilities.

    Porbabilities of Girls
    x(girls) P(x)
    ======== ====
    0 0.000
    1 0.001
    2 0.006
    .
    .
    13 0.001
    14 0.000

    How did he get the following:
    P(x) = 0.000
    P(1) = 0.001
    P(2) = 0.006
    P(13) = 0.001
    P(14) = 0.000

    Please explain in simple and detailed steps.
