It is not possible to answer the question for a number of reasons.
The gender of children are not independent of one another. They depends on the parents.
Second, the feeble-mindedness of the child or otherwise is greatly influenced by their nurture: the family and school play an important role in that context. This will affect feeble-minded boys equally.

What is the probability of a family having a boy after four girls?
The probability of a boy is still 0.5 no matter how many prior children there are.
What is the probability of a couple having at least four girls if they have six children?
3 out of 7
What is the probability that a family with four children has all boys given that the first two are boys?
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. However, if you assume that they are independent events then, given that the probability of a boy is approx 0.52, the probability of the other two being boys is 0.2672.
What is the probability of tossing four coins and getting four heads if the first two tosses are heads?
The conditional probability is 1/4.
What is the probability of tossing four coins and getting tails on all four?
Assuming it is a fair coin, the probability is 1/24 = 1/16.
What is the probability that in a family of four children that all four children are girls?
The probably of four girls in a family with four children is 1/16. I got this answer because: Probability of a girl is 1/2 and to get all girls you would multiply it by 1/2 for the rest of the girls.

In a family with four children, the probability of having four boys is 1 in 16.
Four children that is probality at least two are girls?
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. However, if you assume that they are independent events then, given that the probability of a girl is approx 0.48, the probability of 2 or more girls is 0.6617.
What is the probability that a couple would have a family of four children two boys and two girls and in that order?
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. However, if you assume that they are independent events then, given that the probability of a boy is approx 0.52 in all cases, the overall probability is 0.0624.
What is the probability that a couple with four children have 2 boys and 2 girls?
1 out of 4. Regardless of what the first two children are, there is a 50/50 chance that each of the following two kids will fulfill the remaining two conditions

1 in 2
Did Clara schumann have any children?
Yes she had 8 children. Four girls and four boys
What is the probability that a family with four children has all girls?
It is difficult to answer this question properly. One reason is that children's genders are not independent of one another: the gender depends on the parents' genetics and their age. The second reason is that the probability of a girl is not 0.50 but approx 0.48. However, if you ignore reality, then the answer is (1/2)4 = 1/16
If a couple has three daughters what is the probability that the next child is a son if they already have three daughters?
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
What is the probability of randomly selecting a four-child family with exactly two boy children?
