What is the ranking of NBA draft, and how to calculate the probability of winning the first prize?

Not LZ, but every table tennis has 10 numbers from 0 to 9, and each team gets different four-digit segments according to the ranking. For example, bobcats are the last one, ranging in number from 0000 to 2000. In the first prize draw, if the table tennis four-digit combination shaken four times in sequence happens to be located in the number section of the Bobcats, the Bobcats will win the first prize draw, and similarly, if it is located in the number section of other teams, the team will win the first prize draw. But not every team has the opportunity to draw lottery, only the team that has not entered the playoffs this season has this right. After the lottery area 14 draft pick, the teams that entered the playoffs this season will be drafted in the order of record ranking from low to high. The same is true in the second round, where league teams will draft in the order of record ranking from low to high. Hope to adopt! !
