发帖数: 1093 | 1 Say I have a deck of 52 cards, regular deck of cards. I put a joker in the
deck somewhere and shuffle it up. Now I
start dealing you cards until the joker shows up. Once it shows up, I stop
dealing you cards. What is the
probability that you have, in your set of cards, all 4 aces? | l*******b

发帖数: 1093 | 3 是发牌的意思，怎么算的？
【在 l*******b 的大作中提到】
: dealing是指给发牌对不，概率是1/5?
| l*******b
发帖数: 2586 | 4 只跟joker A A A A的排列有关，joker 排最后的概率是1/5
