What is the probability of 4 boys in a family with 4 children?
In a family with four children, the probability of having four boys is 1 in 16.
What is the probability that a family of four children has at least 1 boy?
1 in 2
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 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 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 you select a family with four children what is the probability of selecting a family with exactly 3 male children?
To determine the probability of selecting a family with exactly 3 male children out of 4, we can use the binomial probability formula. The probability of having a male child is typically considered to be 0.5 (assuming an equal likelihood of male and female). The probability of exactly 3 males in 4 children is calculated as ( P(X = 3) = \binom{4}{3} (0.5)^3 (0.5)^1 = 4 \times 0.125 \times 0.5 = 0.25 ). Thus, the probability is 0.25 or 25%.
What is a four child family's odds against having four boys?
The odds of a four-child family having four boys can be calculated using the probability of each child being a boy, which is typically 1/2. Therefore, the probability of having four boys in a row is (1/2) × (1/2) × (1/2) × (1/2) = 1/16. This means the odds against having four boys are 15 to 1, as there are 15 other combinations of boys and girls possible in four children.
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.
In a family of four children what is the probability of having exactly two daughters assuming sons and daughters are equally likely?
50-50
What is the chance of having a family of three girls and four boys using binomial sampling?
In a world in which every family has seven children (quite unlikely!) the probability would be 35/128 = 0.273. However in the world that we live in, families with 7 children are very rare and so the answer would be 0.273 of that very rare proportion.
