If you were going to make a wager on who will be our next president, you might place a bet on-line or at a window in Las Vegas. But before you do, you need to understand the "odds."
Paddy Power Sports Betting (h/t Lynn Reder, Carnegie Mellon U)has the odds for the US race for President as 2/7 for Clinton and 2/1 for Trump. If you are like me, and you think Las Vegas is for food, not gambling, then you need some help as I did to understand those odds, so here's a primer on betting odds at the track.
How do betting odds work?
Betting odds are usually expressed as fractions, 2/1, 7/2 and 6/4 as examples. With the aid of a simple calculator or spreadsheet we can calculate how much we can win from a bet and also the percentage chance of our chosen selection. Let's start with the first odds mentioned, the 2 to 1 chance, written as 2/1. We can find the percentage chance of the 2/1 shot winning by adding the right hand side (1) to the left hand side (2) giving us 3, the right hand side (1) is then divided by 3 giving the answer 0.333 or 33.3%. Now we can calculate any odds that are expressed as fractions. Let's try the 7/2 chance, add the 2 to the 7 giving 9 and divide 2 by 9 which gives us 0.222 or 22.2%. The 6/4 shot has a 0.40 (40%) chance of winning, 4 added to the 6 (10) 4 divided by 10 = 0.4, it's that simple. Awkward odds like 13/8 can easily be calculated, 13 + 8 = 21, 8 divided by 21 = 0.38 (38%).
Now we can do that simple math on the odds for president. For Clinton, 2+7 = 9, 7/9 = 77.7%. For Trump, 2+1 = 3, 1/3 = 33.3%. So the betting odds are that Clinton is over twice as likely as Trump to take the Presidency. Other sites, like OddsChecker, have similar odds: 4/11 for Clinton and 2/1 for Trump are representative of the 16 sites reported. What about Sanders? Representative odds are 33/1.
None of that is terribly surprising. It just quantifies what is already in the media. How about something a little more challenging and not widely reported, like the Vice Presidential picks? Below I list some I find interesting.
For Democrats: Julian Castro (5/2), Tim Kaine (5/1), Elizabeth Warren (7/1), Sherrod Brown (10/1), Bernie Sanders (16/1), Clinton (25/1).
For Republicans: Kasich (3/1), Christie (4/1), Gingrich (4/1), Cruz (14/1), Fiorina (25/1), Ryan (33/1).
