    Try this one:

    A man was to be sentenced, and the judge told him, "You may make a statement. If it is true, I'll sentence you to four years in prison. If it is false, I'll sentence you to six years in prison." After the man made his statement, the judge decided to let him go free. What did the man say?

    If the proportion for every new born, boys or girls) is of 0.5 for each of them, it remains the same ad infinitum, no matter the number of families having children is more and more less.

    This is an answer at first puzzle with the proportion of boys and girls
