2. There are 20 marbles in a bag. 8 are blue, 3 are red, and 9 are green. What is the probability of pulling

out a blue marble?

Answer:2/5

Step-by-step explanation:8 out of 20 marbles reduces down to 2/5.

Step-by-step explanation:

Answer: 8/20 or a simplified answer is 2/5

You know that there is 20 marbles in the bag. But you need a blue one so you are wanting one of the 8 blue ones that are in the bag. So you have 8/20 chance of getting a blue marble. If you need a percentage then do 8 divided by 20.
