In the US, the probability of a baby being a boy is 0.512. Among the next ten randomly selected births in the US, what is the probability that at least one of them is a girl.

Expert Solution

Probability of a boy = 0.512

Probability of a girl = 1 - 0.512 = 0.488

n = 10

P(at least one girl) = 1 - P(no girl)

= 1 - P(all 10 boys)

= 1 - (0.512)^10

= 0.9988 (approx)

Hence, the required probability is 0.9988 (rounded to 4 decimal places)
