Answer: 0.9887
Step-by-step explanation:
Given : The true probability of a baby being a boy : [tex]0.527[/tex]
The number of selected births : [tex]7[/tex]
Now, the when next seven randomly selected births in the country, then the probability that at least one of them is a girl is given by :_
[tex]\text{P(at least one girl)=1-P(none of them girl)}\\\\=1-(0.527)^7=0.988710510435\approx0.9887[/tex]
Hence, the probability that at least one of them is a girl =0.9887
