5 over 20
The sum of the probabilities of all the sections must equal 1 (since the arrow must land on one of the sections).
Probability of landing on a red section: 9/20
Probability of landing on a blue section: 6/20
Therefore, the probability of landing on a green section can be calculated as follows:
1 - (9/20 + 6/20) = 1 - (15/20) = 5/20
So, the probability of the arrow landing on a green-colored section is 5 over 20.
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 9 over 20 . The probability of the arrow landing on a section colored blue is 6 over 20 . What is the probability of the arrow landing on a green-colored section? 15 over 20
11 over 20
6 over 20
5 over 20
