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?

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) =

P(at least one girl) = 1 - p(5 boys) = = 0.96049

Hence, the probability is 0.96049.
