What are the possibilities for 1 X 2 – according to the bookmaker, and how does he profit?
The example is the match Chelsea – Arsenal with these coefficients
1-2,00 |Х-3.00 |2-4.00
Index for 1 = 1/2.00 = 0.50 in percent = 50
Index for Х = 1/3.00 = 0.33 in percent = 33
Index for 2 = 1/4.00 = 0.25 in percent = 25
We sum all and get the total index for profit for bookmaker – 1.08 0.5+0.33+0.25 = 1.08 It used to be 1, but here is the deal for the bookmaker, this difference 0.008 is called margin. What is this all about, bookmaker is decided that the chances for Chelsea are 46% – this is 2.17 coefficient but he gave to you lower coefficient – 2.00 ( then higher percentage – 50%) and what happens if there is 100 bets on 1 in 2.00, will be hit 46 matches which is 92 profit with 100 bet.
The part that bookmaker pay – 92%
It is equally of 100% x (1 / total index of profit of the bookmaker) or:
100 x 1/1.08
100 x 0.92
92%
Here calculations show that you really get 8% less, than really must be. This is the bookmaker profit.
The real value of the different prognoses according to the bookmaker:
Index for 1 * Part paid by the bookmaker
Index for Х * Part paid by the bookmaker
Index for 2 * Part paid by the bookmaker
I.e.
0.50 х 92 = 46%
0.33 х 92 = 30,66%
0.25 х 92 = 23%
Total ~100 %
Actually this is the real values, which the bookmaker has given for 1 X 2, before putting the bookmaker diversion.
