Ответ:
To find the probability of choosing a red card we need to add both the cards so we have a total amount of cards.
17 + 9 = 26
Since, the question is asking the probability of choosing a RED card then the probability is a 17/26 chance. The answer choices are written as ratios. The ratio that is the same to 17/26 is [ D. 17:26 ]
Best of Luck!
