Calculator Use
The under 3.5 goals is priced at 1.3 or 3 to 10. SO you divide 1 by 1.3 and you get 0.769. Multiple this by 100 to get the expected probability = 76.9. SO the bookmakers have an expected probability of under 3.5 goals in the game of 76.9%.
35 Odd Or Even
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.
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)

3/5 Odds As A Decimal
To make the payouts simpler, some casinos are now offering 3-4-5x Odds, in whichthe payout is always seven times the amount of the Pass or Come wager, assumingthe player takes the maximum odds. But in order to simply the payout they had tomake the wagering more complicated. The maximum for your Free Odds bet depends onthe point: 3x on the 4 or 10, 4x on the 5 or 9, and 5x on the 6 or 8. Are 3-4-5Odds good or bad? It depends on how you play:
- If you don't take the maximum odds when you play then you're throwing yourmoney away anyway and it doesn't matter what table odds the casino offers.
- If you take full odds and normally play at a table with single, double, or 3xodds, then 3-4-5x odds will give you a lower house edge.
- If you take full odds and normally play at a 5x table, then 3-4-5x givesyou pretty much the same game. The 3-4-5x odds are just a tiny amount worse than5x odds (0.374%, compared to 0.326% for a 5x table), but your expected hourly lossis identical. (You have the same 1.41% edge on the $5 Pass Line bet either way,and there's no edge on the Free Odds bet.)
- If you take full odds and normally play at a 10x or better table, then playingat a 3-4-5X table will give you a worse game.

Origins of 3-4-5X Odds
35 Offset Mount
Reliable sources (a boxman and floorman at Bally's) tell us that 3-4-5X odds wasthe idea of a high-rolling player named Stanley L., sometime around the early 90's.(We believe we know his last name but decline to reveal it for the sake of privacy.)Because he was a high roller, one side of a table that was reserved solely for hisplay. As Stanley was strictly a Pass Line and Come player, he convinced the crapspit at Bally's to allow him to use the 3-4-5X odds as it was easier for him to understandthe pay offs on wins, since every win meant the same payout — seven times the flatbet on wins where full free odds were taken. What we don't know is what the originaltable odds were. That is, did the casino raise the odds from 2X upward orreduce from 5X downward?

What ever happened to Stanley L.? It was stated that he ran up over a million dollarsin markers and was never seen again.
