ABSTRACT
In chapters 3 and 4 we examined various views of chances, like the chances of coin tosses landing heads, of male or female births, of catching infectious diseases, or of radioactive atoms decaying in various periods of time. In all these examples, and on any view of chance, there is an undeniably close link between chances and such actual frequencies as the fractions of actual coin tosses that land heads, of births that are male, of people who catch diseases and of atoms that decay in any finite time.
