Suppose that a certain society values sons more than daughters.
In this society, a couple will continue bearing children until they
produce a son, at which point they will retire from the child
bearing business.

Would this familyplanning scheme tend to produce more boys,
or more girls?

Using coin tosses, simulate the generation of twenty families.
What is the ratio of sons to daughters?
Make histograms for the number of sons and the number of
daughters. Find the average
number of sons and the number of daughters,

If couples could magically determine the sex of their offspring,
what would happen? Would there be a sudden increase in the
number of boys, or girls? If so, would this imbalance correct
itself?

If society were able to prevent the use of this magical method,
would it have the right to do so? If so, would it be welladvised to
do so?
