I am new to this site and wondering if anyone has the formula for determining a trifecta payout and a first4 payout.

I currently have one formula for the trifecta which is: (H1 x [(H1 x H2) - 1] x (H3 + 1)/(H1 + 1)) - 1, where H1,H2 and H3 are the odds for the selected runners.

Can anyone confirm if this is correct, and any takers for the first4 formula?

Any assistance provided to a frustrated mathematically-challenged punter would be appreciated.
