Simulation. A classic probability problem involves a king who wants to increase the proportion of women in his kingdom. He decrees that after a mother gives birth to a son, she is prohibited from having any more children. The king reasons that some families will have just one boy whereas other families will have a few girls and one boy, so the proportion of girls will be increased. Use coin tossing to simulate a kingdom that abides by this decree: “After a mother gives birth to a son, she will not have any other children.” If this decree is followed, does the proportion of girls increase?
