mathematical equation for baccarat using 8 decks

Good day,

With all the possible combination of Player, Banker and Tie to win listed in the Wizard of Odds using 8 decks, how do you translate it into mathematical equation?
I wanted to show an equation that will compute either Player or Banker being beaten (by natural 9 of the opposite side) while having natural 8 points.
Wizard of odds shows the following combination:

Player Banker Combination
8 (Natural) 9 (Natural) 44,858,924,089,344
9 (Natural) 8 (Natural) 44,858,924,089,344
Total 89,717,848,178,688
Total Deals Overall 4,998,398,275,503,360
Probability 0.0179493196087207

Thanks for the help....
