In humans, the sex of an offspring, a boy or a girl is determined by the combination of sex chromosomes inherited from the parents. What is the possibility of having a boy offspring in the family? Determine the experiment, sample space, event and outcome.

Answer:
Experiment: Determining the sex of an offspring in a family
Sample Space: The possible combinations of sex chromosomes that can be inherited from the parents are XX (female) and XY (male).
Event: Having a boy offspring in the family.
Outcome: The outcome can either be a boy (XY) or a girl (XX).
To determine the probability of having a boy offspring in the family, we need to consider the possible outcomes and their likelihood. Since there are only two possible outcomes (boy or girl), the probability of having a boy is 1/2 or 50%. This assumes that the parents do not have any genetic factors that may affect the likelihood of having a boy or a girl.
It's important to note that while the probability of having a boy or a girl is equal, this does not guarantee that a family will have both boys and girls. In reality, there can be variations from this probability due to genetic factors or chance.
