If mathematics was the only skill required for winning, the best players would all be mathematicians - and they're not. Knowing your opponents is also important.

Pick 6. This wager requires the player to select the winner of six consecutive races prior to the first race of the pick six. Some tracks place the pick six as the first six races, the middle six races, or the last six races. Many tracks have carry over pools for the pick six that can grow to as high as a million dollars.

The race is not always to the swift nor the battle to the strong, but that's the way to bet. ~Damon Runyon
