A spinner is divided into many sections of equal size. Some sections are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 12/20. The probability of the arrow landing on a section colored blue is 6/20. What is the probability of the arrow landing on a green-colored section? ​

12 + 6 is 18 so then your remaining would be 2 so your answer should be 2/20!

Answer:

[tex]\frac{2}{20}[/tex]

Step-by-step explanation:

We have 3 sections.

  1. [tex]\frac{12}{20}[/tex]
  2. [tex]\frac{6}{20}[/tex]
  3. [tex]\frac{x}{20}[/tex]

Since we only have 3 sections, we can add red and blue, and subtract  [tex]\frac{20}{20}[/tex]

[tex]\frac{12}{20} + \frac{6}{20} = \frac{18}{20}[/tex]

Subtract:

[tex]\frac{20}{20}-\frac{18}{20} = \frac{2}{20}[/tex]
