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? ​

Answer:


(2)/(20)

Explanation:

We have 3 sections.


  1. (12)/(20)

  2. (6)/(20)

  3. (x)/(20)

Since we only have 3 sections, we can add red and blue, and subtract
(20)/(20)


(12)/(20) + (6)/(20) = (18)/(20)

Subtract:


(20)/(20)-(18)/(20) = (2)/(20)

Answer:

2/20

Explanation:

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