My son can't understand why I don't do the lottery. I pointed out Adam Smith's wise words on the subject. "In order to have a better chance for some of the great prizes, some people purchase several tickets, and others, small share in a still greater number. There is not, however, a more certain proposition in mathematics than that the more tickets you adventure upon, the more likely you are to be a loser. Adventure upon all the tickets in the lottery, and you lose for certain; and the greater the number of your tickets the nearer you approach to this certainty."
