I have $12$ face cards ($4$ kings, $4$ queens, $4$ jacks). What is the probability that I’ll pick $2$ red queens if $5$ cards are chosen?
My answer is $\frac{\binom{10}{3}}{\binom{12}{5}} = \frac{5}{33}$, since the number of ways to choose the other 3 cards once the 2 red queens are already chosen is $\binom{10}{3}$, and the number of ways to choose the 5 cards is $\binom{12}{5}$.
I seem to be missing out something here, particularly on the part when choosing the $2$ red queens.
Can anyone help me point out my mistake? Thank you!
