A deck has 12 cards numbered 1 to 12. Ashley needs a number greater than 9 to win a game. If she selects a card at random, what is the probability that she will win?

so she need one of 10, 11, or 12

prob of that = 3/12 = 1/4

(3x-y)(2x-y

To find the probability of Ashley winning the game, we need to determine how many favorable outcomes (number greater than 9) there are and divide it by the total number of possible outcomes.

First, let's determine the number of favorable outcomes. We know that Ashley needs a number greater than 9, which means she can choose from the cards numbered 10, 11, or 12. So, the number of favorable outcomes is 3.

Next, let's determine the total number of possible outcomes. Since there are 12 cards in total, Ashley can choose from any of those cards. So, the total number of possible outcomes is 12.

Now, we can calculate the probability by dividing the number of favorable outcomes by the total number of possible outcomes:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
= 3 / 12
= 1 / 4

Therefore, the probability that Ashley will win the game is 1/4 or 0.25, which can also be expressed as 25%.
