The sum of the list chances would be * J for (1) and 

 |f for (2) ; and consequently it would be possible to 

 make a profit on a "book " with either of these lists. 

 As I am not at present concerned with the actual 

 practice of betting, I need not discuss such questions as 

 to the probability of the " fielder" " getting round." 



For (1) list of prices just quoted, the following would 

 be a " round" book - 



50 to 75 against A. (2 to 3 against). 

 100 to 33 ,, B (3 to 1 ). 

 100 to 33 C(3tol ). 



If A won, the " bookie " would win 66-50=16 ; if B, 

 108-100=8; and if 0,108-100 = 8. 

 And for "list" (2) : 



75 to 75 against X (evens). 



100 to 50 Y (2 to 1 against). 



100 to 33 Z (3 to 1 ). 



In this case, if X won, he would gain 83 75=8 ; if 

 Y, 108-100=8; and if Z, 125-100=25. 



The odds of one horse against another in the 

 same race is the proportion which their respective 

 chances bear to each other. Thus, if A be at even 

 money (| chance) and B at 2 to 1 (^chance), the 

 correct betting on A against B (one to win) would be 

 3 to 2. 



The combined odds of two or more horses in the same 

 race is obtained by taking their combined chances. 

 For example, if A was a 5 to 4 on, B 8 to 1 against, and 

 C 17 to 1 against, their combined chance theoretically 

 would be f + + A = it J an d then their combined 

 odds, 13 to 5 on.
