What is the probability that a family with 4 children would have at least 1 boy?
1/4
What is the probability that a couple with three children will have at least one girl?
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%
Find the probability that in a family of 4 children will be a at least 1 boy b At least 1 boy and 1 girl Assume that the probability of a male birth is 12?

What are the odds that they have at least one daughter and one son if a family have 2 children?
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 a daughter and a son in two children is approx 0.4994
Each child in a family has at least three brothers and two sisters What is the smallest number of children the family might have?
Some families have only one child or two at the most because either with one child they could not have more children or didn't want more children and many families feel two children is enough.
Find the probability that in a family of 4 children will be a at least 1 boy and 3 girls?
There is no simple answer to the question because 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 answer is 0.2331.
A woman is chosen at random among all woman who have two children She is asked if she has at least one son and says yes. What is the probability of here other child being a boy?
Children's genders are not independent and therefore there is no simple answer. However, if you do assume that their genders are independent then the probability is 1/3.
