for trifectas you need the winner #5 on top...I posted the finish order of the horses I picked. My horses in the tri-fecta were 5-10-15 and 5-6-17. I know how to bet, but not how to pick a horse.
or in a box with the 2nd and 3rd horses...in a 20 horse field there are 6840 combinations of 3 numbers... Originally Posted by stevepar
