Card Game Probability, the 15th card

73 Views Asked by At

Playing a card game in which 2 52 card decks are combined to create the pile and from this pile each player is dealt 14 cards. One rule of the game is if any player is dealt 3 doubles (a double being a card with same suite and value) a re-shuffle is permitted. However if a player is accidentally dealt 15 cards and is found to have 3 doubles what is the probability that the 15th card completed the three doubles.

If there are $15$ cards dealt with exactly three doubles

then there are $6$ cards of the $15$ which are in the doubles

so the probability one of these $6$ was the last of the $15$ to be dealt is $\dfrac6{15}$
