Question 844755
 In a certain country, the true probability of a baby being a girl is 0.483. Among the next seven randomly selected births in the country, what is the probability that at least one of them is a boy?
-----------
Binomial Problem with n = 7 ; p(girl) = 0.483 ; p(boy) = 0.517
----
P(at least one boy) = 1 - p(7 girls) = 1 - 0.483^7 = 0.9939
