Toto: Tell me Jack, is there any way I can find out what are the odds I will ever make a living from my pen as a self-published writer?
Jack: Sure, it is just a matter of gathering the numbers and averaging them.
Toto: What do you mean?
Jack: Well, let say for example you want to find out what is the proportion of boys and girls who go to college.
