What is the probability of getting either blue or green on a spinner that is 3/10 greens and 1/5 blue?
Semmy [17]

Answer:

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.

\frac{3}{10}+\frac{1}{5}  = ?

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

\frac{1*2}{5*2} =\frac{2}{10}

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

\frac{3}{10} +\frac{2}{10}=\frac{5}{10}

\frac{5}{10} =\frac{1}{2} or 0.50
