So... what are the chances of Villa being safe by next Saturday evening? Let's assume the bookies know what they are talking about and do a bit of maths...
The only matches that matter (as far as this question is concerned) are Southampton v Villa and Spurs v Hull. If Hull get more points than us on Saturday, we will go into the final day with relegation still a possibility (whatever the results in other games). If they don't, we are safe.
Based on the bookies' odds I've seen, the probabilities for those two games are (adjusting slightly to make the probabilities add up to 1):
Soton v Villa: Soton win: 0.54 Draw 0.26 Villa win 0.20
Spurs v Hull; Spurs win: 0.56 Draw 0.24 Hull win 0.20
So, by my reckoning, the probability of Villa being safe from relegation after those games would be:
Probability (Villa win) + Probability (Villa Draw + Hull Draw or Lose) + Probability (Villa Lose + Hull Lose)
= 0.20 + (0.26 x 0.80) + (0.54 x 0.56)
= 0.20 + 0.208 + 0.302
= 0.71
We therefore have (based on the bookies' odds) about a 71% chance of being safe by Saturday evening, and a 29% chance of not being safe (either then or at kick-off on the last day of the season).
Let's hope the more likely thing happens.
