A large bag of marbles contains an equal amount of red, orange, yellow, blue, and green marbles. Quinn randomly selects 1 marble from the bag. Which of the following represents the probability of selecting a red or blue marble?

Answer 1

Since there are equal of each and there are four colors it is out of four, now because it is an equal amount of each color and there are two colors then there is a 2/4 chance of pulling a red or blue marble.
