A box is filled with 10 brown cards , 4 yellow cards, and 4 red cards. A card is chosen at random from the box. What is the probability that the card is not red? Write answer as a fraction in simplest form
explanation: 10+4+4= 18 cards in the box and there are 4 red cards in the box, so it’s 4/18. u divide both sides by 2, which gives u the simplest version, 2/9.
