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 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 greencolored section?
2 over 20
6 over 20
8 over 20
18 over 20

Best ResponseYou've already chosen the best response.0\(P(red) = \dfrac{number ~of~red ~sections}{all~sections} = \dfrac{12}{20} \) \(P(blue) = \dfrac{number~of~blue ~sections}{all~sections} = \dfrac{6}{20} \) From the fractions above, what does it look like are the numbers of red sections, blue sections, and all sections?

Best ResponseYou've already chosen the best response.0red = 12; blue = 6; all = 20 green = 20  red  blue = 20  12  6 = 2 P(green) = 2/20
