Question

A bag contains 9 marbles. Three marbles are red, two are green, and the others are blue. What is the probability that a blue or green marble will be chosen? Give your answer as a ratio. (Remember to reduce if needed.)

Answer 1

2 : 4

green : blue

Explanation:

if there is 9 marbles in the bag and 3 are red and 2 are green then 3+2= 5 so 9-5 = 4 so there 4 blue marbles

hope this helps

Answer 2

2:3

Explanation:

9marbles - redmarbles=6marbles

6/9

To simplify the ratio 6:9, we find the greatest common divisor of 6 and 9, and then we divide 6 and 9 by the greatest common divisor. The greatest common divisor that you can use to simplify 6:9 is 3. Which means the answer to ratio 6:9 simplified is: 2:3. Here is the math to illustrate better: 6/3 = 2 and 9/3 = 3.
