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) = $1-0.524=0.476$

P(at least one girl) = 1 - p(5 boys) = $1-0.524^5$ = 0.96049

Hence, the probability is 0.96049.
