Vadim26 [7]

The probability of a baby being a boy is 0.514.

Nine baby births are selected and we have to find the probability that at last one of them is a girl.

P(At least one out of 9 is baby girl) = 1 - P(No baby girl)

= 1 - P(All 9 are baby boy)

= 1 - (0.514)^9

= 1 - 0.0025

= 0.9975

The probability that at least one out of 9 selected births is baby girl is 0.9975
