Question

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 9/20 . 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? (1 point)

A. 11/20
B. 5/20
C. 15/20
D. 6/20

Answer 1

Answer: B. 5/20

Step-by-step explanation: We have 3 sections. Red, blue, and green. Red is 9/20, blue is 6/20. If we do 9+6, it equals 15. Since it's out of 20, you have to do 20-15 which equals 5. Your answer is 5/20.
