What is the draft pick in NBA?

The NBA began to draw lots from 1985. Every year when the playoffs are in full swing, the NBA will convene teams that fail to enter the playoffs to hold a lottery ceremony to decide the ownership of the top three draft picks in the future. In the lucky draw ceremony, the host will take out 1- 14 ping-pong balls and put them into the container. Four balls are randomly selected from 14 balls, regardless of numerical order. A * * can produce 100 1 possible combinations. Before the draw, the teams that didn't qualify for the playoffs had been ranked in reverse order according to the regular season record, and the corresponding combination number (probability) of winning the first prize was obtained.
