Background:
Oddschecker normally displays odds in 'odds' format, for example Trump is 11/17 (pronounced "eleven for seventeen" or "eleven to seventeen" - depending on where in the world you are). To a non-gambler, that doesn't mean much. But 60.7% is much more meaningful.
Helps to use betting markets to infer real-world probabilities. Not perfect, but somewhat informative.
