DOUBLE EVENT BETS. 225 



A double event bet is, also, calculated by taking 



the chances, which in this case are multiplied together. 



Thus, if it be 3 to 2 in favour of a certain occurrence 



taking place, and 10 to 1 against another event 



occurring, the chance of their both happening will be 



x TT=/5- ; and the odds 52 to 3, or 17i to 1 against it. 



Lotteries, In lotteries the number of tickets and 



their prices vary ; although at the principal meetings 



they are generally fixed at a 100, and Ks. 10 respectively. 



The honorary secretary, or some other official, should, 



first of all, write down the tickets taken by single 



individuals, and then those taken conjointly ; the 



practice being to throw with dice for tickets, for which 



the loser pays, although both he and the winner 



equally share the amount obtained for the chance of 



any horse which any of their tickets may draw. Not 



until all the tickets which can be disposed, either 



individually or conjointly, are written down, should 



sweeps be allowed to take place ; for they always tend 



to check the other forms of ticket-taking. 



A lottery may be made out on a large sheet of foolscap, 

 on the first and second pages of which the tickets are 

 written down. At the end of the second page there is 

 a form for recording the result of the drawing ; and on 

 the third page one for showing the debit and credit 

 of each person. 



I shall now give an illustrative lottery paper for a 

 race, in which we may assume that 5 horses, viz., Mr. 

 Johnson's Sam, Mr. Williams' Jack, Mr. Payne's Lucy, 

 Mr. Thompson's Kuby, and Mr. Smith's Brilliant, are 

 declared to start, that there are 50 tickets at Ks. 10 

 each, and that Lucy won. From the total amount of
