    The probability of a baby being a boy is 0.514.

    Nine baby births are selected and we have to find the probability that at last one of them is a girl.

    P (At least one out of 9 is baby girl) = 1 - P (No baby girl)

    = 1 - P (All 9 are baby boy)

    = 1 - (0.514) ^9

    = 1 - 0.0025

    = 0.9975

    The probability that at least one out of 9 selected births is baby girl is 0.9975
