In a certain​ country, the true probability of a baby being a Girl is 0.469.
Among the next Nine randomly selected births in the​ country, what is the probability
that at least one of them is a boy ?
~~~~~~~~~~~~~~~~~~~~

The event  "at least one of them is a boy" is the complement to the event "no one of them is a boy".


Therefore, the answer to the question is

    P = 1+-+%281-0.469%29%5E9 = 1+-+0.531%5E9 = 0.9966  (rounded).

Solved.
