Odds of WinningEach lottery team is assigned sets of numbers -- the number of sets is determined by the standings, with the worst team in the league getting the most sets, the second-worst getting the second-most, etc.
Numbers are drawn by private auditors, and the results are announced on live television.
Odds of winning are as follows -- "Team 1" represents the league's worst record, while team 14 would be the non-playoff team with the best overall record:
- Team 1 - 250 combinations (25.0%)
- Team 2 - 199 combinations (19.9%)
- Team 3 - 156 combinations (15.6%)
- Team 4 - 119 combinations (11.9%)
- Team 5 - 88 combinations (8.8%)
- Team 6 - 63 combinations (6.3%)
- Team 7 - 43 combinations (4.3%)
- Team 8 - 28 combinations (2.8%)
- Team 9 - 17 combinations (1.7%)
- Team 10 - 11 combinations (1.1%)
- Team 11 - 8 combinations (0.8%)
- Team 12 - 7 combinations (0.7%)
- Team 13 - 6 combinations (0.6%)

Draft Lottery HistoryThe first NBA Draft Lottery was held in 1985. At the time, every non-playoff team had an equal shot at the top pick. The New York Knicks won the lottery and the right to draft Georgetown center Patrick Ewing.
One of the most enduring NBA conspiracy theories suggests that the lottery was fixed in an attempt to prop up the franchise in America's biggest media market. According to legend, the envelope containing the Knick logo was frozen so NBA commissioner David Stern would know it by touch.
Changes to the Lottery ForamtThe league has made several changes to the lottery format since then.
- 1987: Only the first three picks drawn by lottery
- 1990: Odds of winning weighted towards the league's worst teams. With eleven non-playoff teams, the worst team had eleven changes to win, the second-worst had ten, etc.
- 1994: Current system implemented, with league's worst team having a 25 percent chance of winning.
