### Fantasy League Draft Lottery Question

Hello.

I have an update to a question that I've gotten an answer to here before (cannot post links, but the thread was called "Probability with draft lottery" if it helps). Our league is expanding to 12 teams now, so I need to update our odds for each pick with a new "ticket" distribution, shown below.

I'm trying to figure out each team's odds of receiving each of the 11 lottery picks in our draft. It's much like the NBA's lottery draft, but there are no limitations as to how much a team can move up or down and we use all 1001 tickets (the NBA drops one).

Can anyone help me figure this out, or point me to where I could learn to simulate the results myself?

Finish    Tickets    Odds of first Pick
12th              300                    30.0%
11th              250                    25.0%
10th              175                    17.5%
9th              100                    10.0%
8th              75                     7.5%
7th              50                     5.0%
6th              25                     2.5%
5th              15                     1.5%
4th               7                     0.7%
3rd               3                     0.3%
2nd               1                     0.1%
1st    No tickets, picks last (12th) automatically

Total Tickets    1001

To perhaps better explain, here is what the results were for the draft when it was only 10 teams (below is what I'm hoping to figure out for the new distribution of tickets).

Odds
Standings    Tickets    1st Pick    2nd Pick    3rd Pick    4th Pick    5th Pick    6th Pick    7th Pick    8th Pick    9th Pick
10th               400    40.0%    30.5%    18.7%    8.0%             2.4%    0.4%            <0.1%    <0.1%    <0.1%
9th               300    30.0%    30.3%    22.5%    12.2%    4.2%             0.9%     0.1%    <0.1%    <0.1%
8th               150    15.0%    18.5%    26.0%    22.7%    12.5%    4.3%             0.8%      0.1%     <0.1%
7th                 75    7.5%            10.2%    15.6%    25.7%    23.4%    13.0%     4.1%      0.6%    <0.1%
6th                 40    4.0%             5.5%    8.8%            15.9%    27.0%    23.9%    11.8%    2.8%              0.2%
5th                 20    2.0%        2.8%    4.7%      8.5%     16.2%    29.2%    25.2%    10.5%    1.1%
4th                 10    1.0%             1.4%    2.3%     4.4%            8.7%            17.3%    33.5%    26.5%    4.7%
3rd                   5    0.5%             0.7%    1.2%     2.2%     4.5%            9.1%            20.1%    47.7%    13.9%
2nd                   1    0.1%         0.1%    0.3%            0.4%     0.9%            1.8%     4.3%     11.8%    80.2%
1st                   0    Champion picks last (10th) automatically

Hi;

but your chart was more readable. This one I am having problems with.

### Re: Fantasy League Draft Lottery Question

Yeah that didn't post as legibly as I'd hoped. Here's the new ticket distribution, laied out as it was in the old post (hoping that's more clear):

Out of 1001 tickets (all of the 4/14 possible combos):

Team 1: 300 tickets
Team 2: 250 tickets
Team 3: 175 tickets
Team 4: 100 tickets
Team 5: 75 tickets
Team 6: 50 tickets
Team 7: 25 tickets
Team 8: 15 tickets
Team 9: 7 tickets
Team 10: 3 tickets
Team 11: 1 ticket

Correct. Nothing but the number of picks (was 9, is now 11) and ticket distribution (as above) has changed.

One more thing, math is newfangled to me so I really only believe in one thing. Did the calculations I provided work last time?

Yes, the calculations from your simulation last time worked perfectly. That's why I came back here

Okay, then I am going to do them the exact same way and hope for the best. I will post the answers here.

Hi;

Hmmm, you will not be thanking me after you have read them all...

Nope, he was happy in the past with a computer solution so I just went with that.

Hi bobbym,

Is the other thread deleted? What are the rules?

Hi gAr;

I am looking for it. I do not see it. I can only presume that the OP has deleted it.

I can provide the rules if you need them.

Here are the exact values for the second pick, I think, if I got the rules correctly:

It appears to be gone. The link in post #2 is going nowhere. I did not touch it, so...

It looks very nasty. I haven't tried to get it for latter draws, because it would involve too many summations.

We have a simpler answer which is good enough for current intents and purposes?

Not exactly, you stated:

I have not even seen the simpler summations you have done!
