When randomly choosing two cards from a standard deck of cards without replacement, what is the probability of choosing a face c
Radda [10]
There are 12 face cards and 4 aces to choose from. For the first card, the probability of drawing a face is \dfrac{\binom{12}1}{\binom{52}1}=\dfrac{12}{52}. Then the probability of drawing an ace second is \dfrac{\binom41}{\binom{51}1}=\dfrac4{51}.

So the probability of drawing these two particular cards in the given order is

\dfrac{12}{52}\cdot\dfrac4{51}=\dfrac4{221}
