a box is filled with 2 blue cards, 2 yellow cards, and 16 red cards. A card is chosen at random from the box. What is the probability that it is a blue or a red card? I got 9/10 Help help

Thank you for the opportunity to help you with your question!

the total # cards is 20, the number of blue or red cards 18, so the probability is 18/20, or 9/10, you are right
