not only online betting but in general like how odds are arrived at and what does it imply? and how people place their bets based on the odds? am not aware of even the fundamentals dude
thx anyways
Odds are the multiplier used in determining the value of a correct bet.
For example, if Australia are at 2.00 (with decimal odds) to win the WC, and you place a $10 wager on them, you'll recieve $20 as a return. If they're at 1.05 you'll recieve $10.50 (so you will effectively only win 50 cents), and if they are at 15.00 you'll recieve $150. There are other odds systems as well, but decimal is probably the simplest one to learn. Most places you can bet will have the odds available in all the major formats.
They're determined by the betting agency you use, so there's sometimes a bit of variation between one betting place and another. Obviously, the more likely a result is, the lower your potential return if you bet on it. If you bet on Glenn McGrath to top the runscoring in the WC you'd get huge odds, whereas Ricky Ponting would pay much less.
As far as how you place your bets goes, there's various ways to do that. If you're betting online, you'll need money in an online account (via credit card or on-site deposit or whatever), and you'll bet out of that, and be paid into it. There's a variety of sites you can use. If you bet face-to-face at a betting agency you'll usually just hand over the money for whatever you are betting on at the time, and there'll be someone there who can guide you through placing a bet.
