the probabilities are exactly the same in the 1-30 lottery as the 30-1 lottery... each ball has a 1/48 chance of being picked at the start-- so... the possible orders of the 48 balls being picked out from 1-30 is the same as the possible orders of the 48 balls being picked out from 30-1.. now just take the 30-1 order, and reverse it to make it 1-30.. so you have a 30-1 order, and a 1-30 order, and in the 30-1 order ignore 2nd/3rd balls, and in the 1-30 order ignore all but the last ball for each team... you get the same result.. and the probability of getting the 30-1 order is the same as getting the 1-30 order
might be a bit confusing to people who havent done stats/finite, but it really is that simple
edit: when i say 1-30 order i really mean the 1-48 ball order, and same thing with 30-1 order (48-1)
I find it hard to take your word because no statistician looks at it that way.
The statistical probability of any one ball being pulled out is all that matters and it changes after every pull.
If you start at 30, and for ease's sake, lets say the Rangers and Blackhawks have three balls each, and every other team only has one.... meaning there are 34 balls....
Each team has a 1/34 chance of being picked, except the Rangers and Blackhawks, who have a 3/34 chance of being pulled out.
If the Rangers and Blackhawks aren't picked, they now have a 3/33 chance of being picked out, while the other teams still only have a 1/33 chance of being pulled.
On the next pick, the Rangers first ball comes out.
Now its:
Blackhawks 3/32
Rangers 2/32
Everyone else 1/32
Next its someone else.
Blk 3/31
Rangers 2/31
Everyone 1/31
Eventually, you will reach a point, and given the odds of lasting, probably well before the tenth overall pick, where the Rangers and Blackhawks catch up with all the remaining teams right about 1/16. It is inevitable that they catch up because of their better chance of being pulled out every time.
So instead of the Rangers and Hawks having a 6% chance to get the first pick and everyone else having a 2% chance, they are now on equal footing to get any particular draft pick from here on out, thus offering the Ranger and Hawks no statistical advantage.
The problem with doing it like this is that the Rangers and Hawks now have pretty good odds at being pulled out at 16 or 15.
This isn't fair, because if you do it the other way, it is
very difficult for the Rangers or Hawks to not have been pulled by 16, since the odds get BETTER when you work the other way.
Given that we are in the business of helping the bad teams out by weighting the system, the only fair way to do it is to start at the front. It protects the interests of bad teams while maintaining reasonable odds for the good teams.
