A spinner has 4 sections. One is green one is yellow, one is red, and one is blue.
What are the odds against the spinner landing on red?
A.) 4:1
B.) 2:2
C.) 3:1
D.) 1:3
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.
To find the odds against the spinner landing on red, we need to consider the total number of possible outcomes and the number of outcomes where the spinner does not land on red.
The spinner has a total of 4 sections, and only one of those sections is red. This means there are 3 sections that are not red.
Therefore, the odds against the spinner landing on red are 3:1.
So, the correct answer is C.) 3:1.
