90% - An EU team makes it out of Groups (giving FNC 75%, G2 50%, and VIT 10% --> 1-(0.25*0.5*0.9) = ~89%)
50% - exactly 1 EU team makes it out of Groups (given the odds above, it would be: only FNC 34%, only G2 ~11%, and only VIT ~1% --> ~46%)
10% - G2 does not make it to Groups (the odds for 90% also imply that G2 would have a ~56% to advance from Groups if they make it there)
Yeah these numbers are a bit high for EU, but I don't think that they are too far off, especially given that G2 would end up in Group A or C.
