that's not how probability works. GES is essentially required to win all 3, mean the probability is 0.7x0.9x0.5, or 31.5% (assuming that your probabilities are accurate, which i would dispute)
Pacific is unpredictable....rrq one day play like a contender, then the other day play like a shit, similar with TS...the only consistent team is dfm...so ges may secure that win...
