What is the probability of getting either blue or green on a spinner that is 3/10 greens and 1/5 blue?

1/2 or 0.50

Step-by-step explanation:

To find the probability of getting either blue or green on a spinner, we must add both probabilities together.

To make adding our two fractions easier, we need to make sure they have like denominators.

Now that the denominators of our probabilities are the same, we can add them together to get our answer.
