The 2013 NBA lottery will be held on Tuesday night May 21st at 6 PM MST. This year the Jazz have a .5 % chance of receiving the number one pick so Jazz fans shouldn’t hold their breath. It should be a fun event though to see who gets the number one pick and the chance at Nerlens Noel or Ben McLemore.
The rules for the Draft Lottery according to Wikipedia are as follows:
To determine the winner, fourteen ping pong balls numbered 1–14 are placed in a standard lottery machine and four balls are randomly selected from the lot. Just as in most traditional lotteries, the order in which the numbers are drawn is not important. That is, 1-2-3-4 is considered to be the same as 4-3-2-1. So although there is a total of 24 (4!) orders in which the balls numbered 1-2-3-4 can be picked, they are all treated as the same outcome. In doing this, the permutation of 4 balls from 14 becomes the combination of 4 balls from 14. That is, the total of 24,024 (14! / 10!, or 14x13x12x11) possible permutations is reduced by a factor of 24, to 1,001 combinations (or 14! / (10! x 4!)). Of these, 1 outcome is disregarded and 1,000 outcomes are distributed among the 14 non-playoff NBA teams. The combination 11-12-13-14 (in any order that those numbers are drawn) is not assigned and it is ignored if drawn; this has never occurred in practice.
In the event a lottery pick is traded to another team, the record of the original team (whose pick it was before the trade) still determines eligibility for the lottery, and assignment of chances.
As of 2008, with 30 NBA teams, 16 qualify for the playoffs and the remaining 14 teams are entered in the draft lottery. These 14 teams are ranked in reverse order of their regular season record and are assigned the following number of chances
- 250 combinations, 25.0% chance of receiving the #1 pick
- 199 combinations, 19.9% chance
- 156 combinations, 15.6% chance
- 119 combinations, 11.9% chance
- 88 combinations, 8.8% chance
- 63 combinations, 6.3% chance
- 43 combinations, 4.3% chance
- 28 combinations, 2.8% chance
- 17 combinations, 1.7% chance
- 11 combinations, 1.1% chance
- 8 combinations, 0.8% chance
- 7 combinations, 0.7% chance
- 6 combinations, 0.6% chance
- 5 combinations, 0.5% chance
