Odds are a price, not a prediction. Once you can convert a price into a probability, most of the confusion around gaming markets disappears.
Decimal odds in one line
Divide 1 by the decimal price and you have the implied probability. A price of 2.50 implies a 40 percent chance. That is the whole calculation.
Why the percentages add up to more than 100
Every market includes a margin. Adding the implied probabilities of all outcomes gives you a number above 100 percent, and the difference is the operator's edge.
Reading a price against the table
When a mid-table side is priced close to a top-four team, the market usually knows something about availability, travel or fixture congestion. Find that reason before you decide the price is wrong.
