Football

I have picked Hull, the other 2 have picked NUFC.

Betfair exchange has the decimal odd for a win as...

Hull - 1.86
Newcastle - 1.81

Convert to probability is 0.54 vs 0.55 (rounded) so...

Hull win/NUFC lose is 0.24
Hull lose/NUFC win is 0.25

a win/win or lose/lose is a roll over. I calculate one or the other to happen to be 0.5.

Could lay this off but, fuck it, I want it all! slight underdog though.

Well, I fucked that up
