What is the probability of drawing an ace and a 10, Jack, Queen, or King from a deck of cards?

  16 out of 52 or 4 out of 13

  I don't understand how you did that. (You're supposed to draw 2 cards - an ace and a 10, an ace and a Jack, an ace and a Queen, or an ace and a King).

  prob = 2(4/52)(16/51) = 32/663 or 0.02413 or using the "choose" notation, C(4,1)C(16,1)/(52,2) = 64/1326 = 32/663
