ou find a deck of cards and know that the deck has too many clubs and spades in it. The deck has 59 cards. If you were to draw t
sashaice [31]
We can find the number of extra clubs in the deck from the given probability, since the probability of drawing a diamond and a club is

\dfrac{\binom{13}1\binom{13+c}1}{\binom{59}2}=\dfrac{13(13+c)}{1711}

but this would imply that c=-4, which suggests we're taking 4 clubs out of the original deck and contradicts the problem statement that there are "too many clubs".

Perhaps the question is providing the probability of drawing a diamond, THEN a club, or vice versa. In that case, we have

\dfrac{\binom{13}1}{\binom{59}1}\cdot\dfrac{\binom{13+c}1}{\binom{58}1}=\dfrac{13(13+c)}{3422}

and solving gives c=5, which makes more sense. Then the number of extra spades in the deck must be 2.
