Based on your location, we recommend that you select: This calculates the probability of finishing 2nd for each horse. The sum of these probabilities adds to one. And we only need all permutations of the first 3 hraville for betting purposes.

See the paper by D. Given every horse’s probability of winning a race, what is the probability that a specific horse will finish 2nd and 3rd?

Looks like you are in error using the prob of 2nd place when computing prob of 3rd. Michael, As you say, it does not make any sense. Is anybody able to tell me these formulas or point me somewhere I can get them?
