If the odds of a horse winning a horse race are 2 to 7 then the odds against that horse winning the race are 7 to 2.
NONE
That means that you have a very slim chance of winning. About a 10% chance of you winning, and a 90% chance of the others winning.
Each year, about 35,000 thoroughbreds are born and registered in the Jockey Club of American. Every one shares the dream of one day making it, and winning the Kentucky Derby. Out of these 35,000, only about 15,000 will make it to the track. Of those 10,000 only 20 can run in the Kentucky Derby, and out of those 20, only one horse can come out victorious. Therefore, the Kentucky Derby is one the most prestigious races in American, and with good reason, too.
No, because that is odds-on.
A horse at 1:1, or even odds, means that for every $2 dollars you bet you will receive $4.
As like most things in a horse race, nothing is ever a sure bet. The odds favorite is more or less an educated guess. It is never written in stone. That is why the horse that was the 'long shot' wins once in a while. Seabiscuit was a habitual 'long shot' early in his career. As he became more successful his odds went up. I always think if you want a sure thing you should ask the horses.
It means a horse that is not likely to win, or that the odds are stacked against him.
In horse racing the odds are determined by the bets placed. Betting stops when the race starts. These determine the final odds.
