Answer:

9) 1/2 (or 1:2, or 50%, or .50, depending on how your teacher wants it.

10) 2/3 (or 2:3, or 66.6%, or 0.66)

Step-by-step explanation:

9) Here are the possibilities of the cards you could pick

KQ, KJ, K10, QJ, Q10, J10

Since there are 6 possibilities and only 3 of them have one face card, the probability is 3/6, or 1/2.

10) It doesn’t matter which card you pick first.  The second card has a 1 in 3 chance of being the same card (whatever it is).  That means you have a 2 in 3 chance of it NOT being the same card.  So the probability is 2/3.
