If the family consists of a pair of parents and their offspring, then the probability is very close to 0.
In a family with four children, the probability of having four boys is 1 in 16.
The probability of a boy is still 0.5 no matter how many prior children there are.

The probability of an individual having either a male or female can not be altered. There is always a 50/50 chance of having a boy or girl. It is not a genetic trait to have one of the other.
We would need to know the number of children in the family to answer this question. For instance, the probability of having no girls in a family of two children would be 1/4 theoretically. In general it is 2-n where n is the number of children.
it is a 50/50 because if you cant get more that 50 % its not
The probability is 1/6.
The probability of having a boy or a girl is always 50/50 each time, regardless of previous outcomes. So the theoretical probability of having a girl after having three boys in a row is still 50%.
