Calculate the cost and return of your double bets.
A double bet combines two bets on separate events into one bet. Their are two types of double bets; one using fixed odds where the dividend is certain and one using a pari-mutuel bet pool where the dividend is unknown.
We can calculate the cost of a pari-mutuel double bet like a Daily Double or a Running Double by multiplying the number of selections in each leg. The winning return is determined by dividing the total betting pool by the number of correct betting units.
The winning return of a double bet using fixed odds is calculated by multiplying the odds of each bet.
