50 1 Odds Explained
Calculator Use
Convert stated odds to a decimal value of probability and a percentage value of winning and losing. This calculator will convert 'odds for winning' an event or 'odds against winning' an event into percentage chances of both winning and losing.
Converting odds to probability fixes 0, sends infinity to 1, and sends 1 to.5 (even odds are 50% likely), and conversely; this is a parabolic transform. Applications edit In probability theory and statistics, odds and similar ratios may be more natural or more convenient than probabilities. So odds of 7-2 mean that for every $2 invested, the punter gets $7 profit in return. This means when you bet $2, the total return if the bet is successful is $9. Similarly, if a horse is at even money (ie 1-1), it’s $2 profit for every $2 invested, or a total return of $4. Or, if a horse is 1-2, it’s $1. For this, betting in $1 increments would be a $6 investment. There are some horse racing tracks that offer 50-cent trifecta betting. The 50-cent trifecta box increment became available for the first time at the 2010 Breeders’ Cup at Churchill Downs. The minimum stake for an online trifecta bet is usually either $.50 or $1. To convert decimal odds to fractional, subtract 1.00 and then find the nearest whole integers (so 3.75 - 1.00 becomes 2.75/1, or 11/4). To convert moneyline odds to decimal, if the moneyline is positive, divide by 100 and add 1. If it is negative, divide 100 by the moneyline amount (without the minus sign) and add 1.
Be careful if you are using sports teams odds or betting odds. If you see that the Patriots super bowl odds are 9/2, that is most likely 'odds against' and should be entered in the calculator with 'Odds are: against winning.'
When playing a lottery or other games of chance be sure you understand the odds or probability that is reported by the game organizer. A 1 in 500 chance of winning, or probability of winning, is entered into this calculator as '1 to 500 Odds are for winning'. You may also see odds reported simply as chance of winning as 500:1. This most likely means '500 to 1 Odds are against winning' which is exactly the same as '1 to 500 Odds are for winning.'
Probability Formulas:
This calculator will convert 'odds of winning' for an event into a probability percentage chance of success.
Odds, are given as (chances for success) : (chances against success) or vice versa.
If odds are stated as an A to B chance of winning then the probability of winning is given as PW = A / (A + B) while the probability of losing is given as PL = B / (A + B).
For example, you win a game if you pull an ace out of a full deck of 52 cards. Pulling any other card you lose. The chance of winning is 4 out of 52, while the chance against winning is 48 out of 52 (52-4=48). Entering A=4 and B=48 into the calculator as 4:48 odds are for winning you get
For 4 to 48 odds for winning;
Probability of:
Winning = (0.0769) or 7.6923%
Losing = (0.9231) or 92.3077%
'Odds for' winning: 1:12 (reduced from 4:48)
'Odds against' winning: 12:1 (reduced from 48:4)

5 1 Odds Meaning
If that sounds like you, we’re here to assist you. If you’ve stared at a board at a sportsbook or just seen spreads and moneylines on the Internet and been utterly confused, don’t worry. It’s not just you. Those numbers can be confounding.
But hopefully, once you’re done reading this, you’ll completely understand how they work. As you prepare to dive into the world of sports betting, here’s a breakdown of how the lines work, starting with …
Spreads
It would be really easy to bet on a game if you could put money on a heavy favorite to win.
That’s where point spreads come in. Let’s look at an example:
Philadelphia Eagles (-4.5)
New York Giants (+4.5)
In this case, you can bet on either two outcomes: you can put money on the Eagles to win the game by 4.5 points OR MORE, which makes them the favorites. Or you can bet that the Giants will either win or lose by LESS THAN 4.5 points. They’re the underdogs.
Now, sometimes the spread “moves” during the days leading up to the game. Perhaps the Eagles’ spread ends up being -3.5 (in which they must win by 3.5 points or more to give you a victory in your bet). Your bet all depends on whichever spread you bet on, whether it was when the Eagles were favored by 4.5 or 3.5 points.
If you ever see “PK” or “pick” next to a team, it means there’s no spread and you can bet on who will win, no matter what the score is.
Moneylines
Let’s take that same example above but use moneylines:
Philadelphia Eagles (-200)
New York Giants (+150)
The team with a minus symbol is the favorite, and the number is how much money you would need to bet to win $100. In this case, you would have to bet $200 on the Eagles in order to win an additional $100.
The Giants are the underdogs. If they’re +150, that means you could bet $100 to win $150.
Note that you can bet any amount you want, but those numbers are always calculated and posted the same way, either in how much money you would need to wager to win $100 or how much money you could win by wagering $100.
Odds
If you’re betting on something like the team who will win the Super Bowl in the future, you might see it look like this:
New England Patriots — 3/1
2 To 1 Odds Mean
Baltimore Ravens — 5/1
Kansas City Chiefs — 8/1
If you were betting on the Patriots and their 3/1 odds, you would win $3 for every $1 you spend. So if you bet $50 on the Pats and they ended up winning the Super Bowl, you’d win $150 (plus your original wager) back.
Is 50/1 Good Odds
Good luck!
