How do I calculate the prob of multiple trifecta's Using the Don Scott methord

Hi Benny,

Not sure what you are actually asking for but if you are looking for a formula to calculate theoretical trifecta dividends then Dr Roger Dedman in his book Commonsense Punting gave us the following formula

{x * [(x*y-1)] *[z+1]/[x+1] -1

where x is odds of winner, y is odds of 2nd placegetter and z is odds of 3rd placegetter.

e.g. if x = $3.00 (2/1), y = $4.00 (3/1), z = $5.00 (4/1)

2*[(2*3-1)]*[4+1]/[2+1] -1

= [2*5*5/3]-1

= 50/3 -1

= 16.67 - 1

= 15.67 to 1

= $16.67

If this is not what you're after then I'm sorry to have wasted your time.

It's just what I need. Thanks

Is there any way that I can use a speadsheet to do the calulations. I take no more than 5 horses which is 60 tickets.

Hi Benny,

If you can list your email address I have put together a spreadsheet you can use for up to 5 horses.

This is my backup email
