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 greencolored section?

Best ResponseYou've already chosen the best response.1x = probability of landing on green \[\Large \frac{9}{20}+\frac{6}{20}+x = 1\] are you able to solve for x ?

Best ResponseYou've already chosen the best response.1we have this now \[\Large \frac{15}{20}+x = 1\]

Best ResponseYou've already chosen the best response.1subtract 15/20 from both sides \[\Large \frac{15}{20}+x = 1\] \[\Large \frac{15}{20}+x\frac{15}{20} = 1\frac{15}{20}\] \[\Large x = 1\frac{15}{20}\] \[\Large x = ???\]

Best ResponseYou've already chosen the best response.15/20 is equivalent to 1/4. I just reduced

Best ResponseYou've already chosen the best response.0The probabilities are equal. The probability of landing on the open end is greater. The probability of landing on the closed end is greater. No conclusion can be made.

Best ResponseYou've already chosen the best response.1so it looks like they didn't reduce the fraction, which is odd

Best ResponseYou've already chosen the best response.1so just don't reduce 5/20
