In a certain country, the true probability of a baby being a boy is 0.524. Among the next five randomly selected births in the
country, what is the probability that at least one of them is a girl?
1 answer:
Answer:
The probability that at least one of them is a girl is 0.96049.
Step-by-step explanation:
In a certain country, the true probability of a baby being a boy is 0.524.
This is a binomial problem.
p(boy) = 0.524
n = 5
p(girl) = ![1-0.524=0.476](https://tex.z-dn.net/?f=1-0.524%3D0.476)
P(at least one girl) = 1 - p(5 boys) =
= 0.96049
Hence, the probability is 0.96049.
