[math-fun] car talk puzzler

Last week's car talk puzzler http://www.cartalk.com/content/puzzlers has an interesting pseudo-probabilty twist. The puzzle (3/14/15, President's Day): My friend, Max says to me, "I just read that three of the first five presidents of the United States died, ready for this? On the Fourth of July. What do you think the odds of that happening are?" I reply, "No idea. But, I'll give you 10-to-one odds that I can name at least one of the three." Now I don't know anything about the first five presidents, he writes, except that their names are: Washington, Adams, Jefferson, Madison and Monroe. In that order. Others might enjoy looking at this, so I won't give my analysis now. Enjoy, Scott
