Answer: D

Step-by-step explanation:

so we know the probability of drawing a 9 is 25 percent or 1/4 because 9 is only one and doesn't repeat.

So the cards we drawn cards we drawn 2 times so multiply 1/4 times two.

1/4 * 2/1= 2/4 = 1/2

Answer:

The answer is D. 1/2 I'm pretty sure. I'm usually pretty good at probability. Keep in mind this may be wrong.

Step-by-step explanation:

There is a 1/4 chance that ONE card drawn will have the number nine. That is only for one though. For 2 cards, it would be a 2/4 chance. Since it is not one of the answers, do the next best thing and simplify the probability. Divide 2/4 by 2 and it equals 1/2.
