Hi.
Let say I have have selected horse A, Horse B and Horse C in Race 1; Horse D in Race 2 and Horse E in Race 3.
What is the formula to get the number of Doubles and the number of Trebles?
thanks

Trebles = 3X1X1 = 3
Doubles = (A,B,C)XD=3 + (A,B,C)XE=3 + DXE=1 = 7 I hope it is clear enough |

It is clear but what is the general formula?

You have to multiply the number of selections of each race.
Race A Sel a b c Race B Sel d e Doubles = 3X2 = 6 ad ae bd be cd ce Race C Sel f g h i Trebles = 3X2X4 = 24 |

For the doubles you could use the formula (T^2-a^2-b^2-c^2...)/2 where T= the total number of horses and a,b,c etc are how many horses are in each race. So if you had 4 races with 2,3,4 and 5 runners, it would be =(196-25-16-9-4)/2 = 71 doubles

Race A - a number of selections
Race B - b number of selections Race C - c number of selections Trebles = a times b times c Doubles = a times b plus a times c plus b times c And so on for more races and quadruples, quintuples, etc. |

Use the Pyramid Block.

....and forget the stake unit because there is none. Then the singles column will hold the number of selections and the doubles column the number of doubles etc.

An Excel based solution:
For 5 horses (or 5 matches) +++ trebles : +++ you have to place in A3 (for example) 5 id of trebles in B3 3 Then in any other cell place this formula: =COMBIN(A3,B3) this gives you the number of trebles for 5 horses (or five matches etc ) (aka 10) +++ doubles : +++ you have to place in A4 (for example) 5 id of doubles in B4 2 Then in any other cell place this formula =COMBIN(A4,B4) this gives you the number of doubles for 5 horses (or five matches etc ) For both trebles and doubles the value is the same : 10 +++++++++ excel help ++++++++++++ COMBIN Returns the number of combinations for a given number of items. Use COMBIN to determine the total possible number of groups for a given number of items. Syntax COMBIN(number,number_chosen) Number is the number of items. Number_chosen is the number of items in each combination. Remarks Numeric arguments are truncated to integers. If either argument is nonnumeric, COMBIN returns the #VALUE! error value. If number < 0, number_chosen < 0, or number < number_chosen, COMBIN returns the #NUM! error value. A combination is any set or subset of items, regardless of their internal order. Combinations are distinct from permutations, for which the internal order is significant. |
