The probability of a baby being a boy is .514 in this country. The probability of selecting 8 babies randomly, all being boys, is .514^8, or 0.004871973887897881805056. Subtract this from 1, you get 0.995128026112102118194944, or a 99.5128026% chance of selecting at least one girl out of 8 randomly chosen infants. ☺☺☺☺
