The odds against the spinner landing on red can be calculated as follows:
- There is 1 red section out of 4 sections in total.
- The number of sections that are not red is 4-1=3.
- So the odds against the spinner landing on red are 3:1, since there are 3 non-red sections for every 1 red section.
Therefore, the correct answer is C.) 3:1.
A spinner has 4 sections. One is green one is yellow, one is red, and one is blue.
