I think that is just a regular poker calculator, I don't see where it calculates the trifecta

Poker Odds Calculator

If PA1, PB1, and PC1 are the respective probabilities of each player finishing 1st, then the probability of player A finishing 2nd and 3rd are (ignoring ties):

PA2 = PB1*PA1/(PA1+PC1) + PC1*PA1/(PA1+PB1)

PA3 = 1 - PA1 - PA2

Put this in a spread sheet I suppose if you want a program to do it for you.

I'm pretty sure this would be inaccurate. Probability for A cannot be for 2nd and 3rd, it has to be the trifecta for the mid stack to go out in 3rd considering the stack sizes. Or maybe I am misunderstanding

I don't think the stack sizes would have anything to do with which player has the best hand and in which order they finish. Maybe you should give a specific example to clarify your question for me.

Do you agree at least my formula for PA3, the probability of player A finishing 3rd, is accurate?

Stack sizes don't have anything to do with the end rankings of the hands but it does affect which order they finish. I didn't include stack sizes in the original post because I just wanted to figure the trifecta probability, but there would be a side pot because of a short stack, medium, and large stack.

As far as the formula I'm afraid it's a bit over my head

OK, it seems you are interpreting the "order of finish" as the amount of chips each player wins?

This is the situation:

Player A:300k
Player B:150k
Player C:30k

I am player B so the only way I get eliminated IN THIRD PLACE is to get beat by player A who also either ties or gets beat by player C in this same hand
