Well are they truly independent?
I don't think they are. Teams performances can vary with psychology. Just like kicking goals. Cloke can probably kick 20 in a row at training. Put him in front of a crowd and.......
If another team wins or loses it can affect the psyche of a team playing another game. True independence does not exist!
Yeah, to an extent. I mean, the probability that Hawthorn beat Sydney in a few weeks might be roughly 0.6. But then you'd also say that the probability that Hawthorn beat Sydney, given that Sydney lost the previous week to Geelong - well that might well be 0.7. Now, given that Richmond can't make the top 4 anymore if Geelong don't beat Sydney, then it's really the probability of Sydney losing to Hawthorn given they lost to Geelong the previous week to work out their chances of making the top 4. We should also apply this thinking to Richmond's games - they are more likely to beat Essendon if they also beat Carlton next week than if you consider the probability independently of next week's match.
If you'd like to use Bayes theorem to adjust the probabilities given by the earlier poster to update the probability, be my guest.
