标题: 请教一段关于AK, AA/KK的计算
今天看到这个:
If we are dealt AdKd, the number of combinations of AA and KK our opponent can have drops from 12 to 6. Since the number of possible combinations drop from 1326 -101= 1225 (there are 51 combinations each with Ad or Kd, which makes a total of 101 unique combinations containing Ad or Kd, since we count AdKd only once), the chance our opponent has AA or KK is 1/204 or 0.5%.

如果是HU,我们拿到AK,对手拿AA or KK的机率是大约0.5%吗?

可以用spreadsheet软件的combin() 这个function 来计算combination
=combin(52,2) = 1326
如果我们拿了两张牌,Ad, Kd 那么只剩下 =combin(50,2) = 1225
对手有 AA, KK的combination 是 =combin(3,2) * 2 = 6
所以是 6/1225 = 0.49%

如果是HU,我们拿到AK,对手拿AA or KK的机率是大约0.5%吗? 对
