There is no simple answer to the question because the children's genders are not independent events. They depend on the parents' ages and their genes.
If you believe that the children's genders are not independent then you would need to get empirical evidence from all families with four or more children in which the first three children were girls. If there are g families in which the fourth is a girl and b where the fourth is a boy then the required probability is b/(g+b).
However, if you assume that the children's genders are independent events then, given that the probability of a boy is approx 0.52, the probability of the fourth child is a boy is 0.52
It is always 50/50.
50% then 25%
50%
Impossible to know without information about genes that the parents have. are the parents colorblind? etc.
it one out 8 1/8 bc first child 1/2 second child 1/2 third child 1/2 1/2 x 1/2 x 1/2 = 1/8

Each time they have a child, there is a 50% chance it will be female.Therefore the chance of getting three daughters in a row is 12.5% (0.5 X 0.5 X 0.5 = 0.125).

The individual probability that a child born will be female is 50% or 0.5.Using this we can calculate the probability that at least one of the children will be female by:calculating the probability that none of the children will be female and then subtracting this from 1.The probability that all the children are male is therefore 0.53 = 0.5 * 0.5 * 0.5 = 0.125.Thus the answer is 1 - 0.125 = 0.875 = 87.5%
It is not possible to answer the question because:the total number of children that the couple had is not known;the gender of the child depends [mainly] on the father, and is not 0.5;the gender of each child is not independent of the gender of previous children.
The probability is 2 - 6
No probability. Neither parent has an "A" for the child to inherit to make an "AB".
There is not enough information on the propensity for the parents to have a child of either gender and so it is necessary to assume that the probability of the gender of the next child is independent of the genders of preceding children. In that case the probability of the next child being a girl is 1/2.There is not enough information on the propensity for the parents to have a child of either gender and so it is necessary to assume that the probability of the gender of the next child is independent of the genders of preceding children.
