I've got a small book titled "Why Buses Come in Threes". The book is about probabilities and some logic problems, and explains them in layman's terms.

In it, the author claims if you are planning to buy a weekly lottery ticket, always wait until Friday. The reason is simple. The odds of you dieing any one day are GREATER than the odds of you winning the lottery. Simply put, if you buy the ticket on Monday, you are more likely to die by Friday than you are to win the drawing. And you would have wasted that dollar.

Having said that, I still by 5 or 10 tickets about once a year - when the amount gets high ($200M or more).
