✔ 最佳答案
六合彩全中的機率係 13,983,816份之1 ( 1 / 13,983,816 ),
而計算的方式係 1/ 49 X 1/ 48 X 1/ 47 X 1/ 46 X 1/ 45 X 1/ 44,
這裡表示的是你想要的number只係其中六個,而在六次中要抽中那六個數,即每次均要抽中其中一個,又因如此, 由49個波開始,你要中頭獎便要抽中在49個波中一個,然後在48個波中一個,之後在47個波中一個,如此類推,最後得出這個機會率。

至於莊家贏廿一點的機會率就比較難計,因有好多唔同情況,但若只是兩人玩,而只抽兩隻牌( 即一條A加一張 J, Q or K )就勝的話,而人地又無抽走你要的牌,
機會率係 4/ 52 X 4/ 50,即 3769/ 5,000,000。
當然,當中仍有好多的因素會影響這個機會率,但在那些因素不變下,這己經是最合理的答案。

計算六合彩頭獎的概率是用combination來計,簡化後的程式如下:

(49*48*47*46*45*44)/(6*5*4*3*2*1)
= 13983816

即是大約1千4百萬分之1的機會.

The probability of winning the Mark Six depends on the number of different combinations of 6 numbers.

Each of the combinations contains 6 balls, that can be arranged among themselves in 6! ways. Therefore the number of combinations equals to 49! / 43! / 6! = 13983816 <-- this is the number of different combinations.

The probability therefore equals to 1/13983816

2007-02-19 18:19:59 補充:
lam points out that the probability of winning Mark Six is 1/49 * 1/48 ... * 1/44 which equals to 10068347520. That is only the number of different arrangements not combinations. The difference is that the order of which number comes first does NOT matter for combinations as for Mark Six.
