NBA Draft Lottery

In Exercises, use the following information. The National Basketball Association (NBA) uses a lottery to determine which team gets the first pick in its annual draft. The teams eligible for the lottery are the 14 non-playoff teams. Fourteen Ping-Pong balls numbered 1 through 14 are placed in a drum. Each of the 14 teams is assigned several of the possible four-number combinations that correspond to the numbers on the Ping-Pong balls, such as 3, 8, 10, and 12. Four balls are then drawn out to determine the first pick in the draft. The order in which the balls are drawn is not important. All of the four-number combinations are assigned to the 14 teams by computer except for one four-number combination. When this four-number combination is drawn, the balls are put back in the drum and another drawing takes place. For instance, if Team A has been assigned the four-number combination 3, 8, 10, 12 and the balls shown at the left are drawn, the Team A wins the first pick.

In how many ways can 4 of the numbers 1 to 14 be selected if order is not important? How many sets of 4 numbers are assigned to the 14 teams?

    NBA Draft( 選秀)Lottery

    NBA用摸彩的方式來決定那一隊可以先挑人。共有 14隊 non-playoff team (未參為季後賽者) 可以參加摸彩. 14個乒乓球由1至 14依次編號放入一圓桶中。每一隊都分配到幾組 4個號碼之組合 (如 3, 8, 10及 12為一組 ). 由桶中抽出 4球來決定那一隊可以先挑人。四個號碼與抽出來的秩序無關. 所有4個號碼之組合都平均分派出去,最後還剩下一組沒分完。如果抽的4個號碼剛好就是剩下來這組的號碼,則會放回重抽。如果抽的4個號碼是3, 8, 10, 12而 A 隊有這一組4個號碼則 A 就可以先挑人.

    從 1 到 14中抽 4 個號碼共會有多少種組合(與秩序無關 )?

    答: C ( 14, 4) = 1,001

    14 隊共分到幾組號碼?

    答: 1,000

    14 隊共分到幾組號碼?

    照 1001 來分每隊可分 71 組 共 994 組. 可是文章中說只有一組沒分出去, 怪怪的. Sorry.

    第二題How many sets of 4 numbers are assigned to the 14 teams?14 隊共分到幾組號碼?

    reply:

    a. 照 1001 來分每隊可分到 71 組因而14 隊 共分到 994 組.

    b. 題目中有說除了一組號碼外,其它都由電腦分配給了14 隊.

    如果只剩一組沒分出去則共分了 1001 - 1 = 1000 組出去。

    我在昨天 6:50 pm 已經補充說明了, 這個地方 a 與 b 不太一致故而怪怪的,不知那裡有誤.

    2008-11-06 11:54:31 補充:

    我找到源頭了http://en.wikipedia.org/wiki/NBA_Draft_Lottery, 第二題答案為 1001 - 1 = 1000, 因為這 14 隊並非機會均等。勝場數最少者分配到 25% ( 250 組) 而勝場數最高者只分配到 0.5% ( 5 組).
