In a certain country, the true probability of a baby being a girl is 0.468. among the next five randomly selected births in the country, what is the probability that at least one of them is a boy

Let B be the event that selected baby is Boy. The probability that baby being a girl is 0.468

P (five selected births at least one is boy) = 1 - P (No boy birth in selected five births)

= 1 - P (all five are baby girls)

= 1 - (0.468) ^5

= 1 - 0.0224

= 0.9776

The probability that at least one of the five selected births is boy is 0.9776
