If an ace is worth 11 points and a jack queen and king of worth 10 points each, what is the probability that you will obtain 21 points with two cards?

We either  draw  the  ace  first  and  then  the king, or  we draw  the king first and then the ace

 

The probability is

 

2 ( 4/52) ( 4/51)   =  32 / 2652   =    8 / 663
