 Three of a Kind (Posted on 2003-11-19)
You have a standard pack of 52 playing cards. You then shuffle them and begin to draw out cards until you have three of a kind. What is the most likely number of cards drawn when this happens?

You then shuffle another pack of 52 playing cards into the pile. What happens to the expected number of cards now? (i.e. does it double / halve / stay the same?)

 Solution??? Comment 39 of 39 |
It's too early in the morning to think....so.
To guarantee 3 of a kind, you must draw 39 cards.
No matter how many more decks you add to the pile, you will still need 39 cards to guarantee another 3 of a kind. Therefore I am going to say ..the chances stay the same.
