There is no simple answer for this.
There are many reasons why a couple may not have children:
- too old,
- same gender,
- the woman is infertile,
- the man is infertile,
- not enough sex
- too much sex
- low sperm count
Narrow down the scope and you have a much better chance of estimating.
If a man and woman are fertile, their chance is extremely high.

Since the probability of having a son is about 1/2, the probability of the first 4 children being boys is about (1/2)4.
The probability of exactly 3 girls in a family of 10 children, assuming equal chance of a boy or girl, is 0.1172. This is a binomial distribution.
Assuming that children of either gender are equally likely, the answer is (1/2)3 = 1/8

Since the probability of having a son is about 1/2, the probability of the first 4 children being boys is about (1/2)4.
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 always 50/50.

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 4 boys and 1 girl out of 5 children is 0.1724 approx.
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.
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
There is no probability. Sorry.
