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.
Assuming the probability of having a girl is 0.5 (the same as having a boy), the probability of a couple having five girls in a row is calculated by raising the probability of having one girl to the power of five. This is (0.5^5 = 0.03125), or 3.125%. Thus, there is a 3.125% chance that a couple will have five girls in succession.
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.

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.

Assuming that children of either gender are equally likely, the answer is (1/2)3 = 1/8
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.
The probability of getting 2 pairs in a poker hand is higher than the probability of getting 3 of a kind.
