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.
[tex]\frac{3}{10}+\frac{1}{5} = ?[/tex]
To make adding our two fractions easier, we need to make sure they have like denominators.
[tex]\frac{1*2}{5*2} =\frac{2}{10}[/tex]
Now that the denominators of our probabilities are the same, we can add them together to get our answer.
[tex]\frac{3}{10} +\frac{2}{10}=\frac{5}{10}[/tex]
[tex]\frac{5}{10} =\frac{1}{2}[/tex] or [tex]0.50[/tex]
