[商管] [統計]-抽牌的機率
A card hand selected from a standard card deck
consists of 2 kings ,2 queens and a jack.
Three additional cards are selected at random and without replacement
from the remaining cards in the deck .
What is the probability that the enlarged hand contains at least three
kings?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
由題目知 每抽到一張牌 丟 3張同樣回去, 可是不重複所以要扣一張走 = 丟兩張回去
請問 可以這樣分析?!
1 - P (每次都沒抽到 K )
3 5 7
= 1 - ( --- + --- +--- ............)
5 7 9
那接下來該怎辦...!?
