A basket contains a red, a yellow, and a green apple. A second basket contains an orange, a lemon, and a peach. Use an organized list to show all the outcomes in the sample space.
(R,O), (R,L), (R, P), (Y, O), (Y, L), (Y, P), (G, O), (G, L), (G, P). There are 9 possible outcomes

A spinner with 8 equal-sized sections is used for a game. Based on the descriptions below, is the spinner fair?
The probability the pointer will land on yellow is 1 out 4.
The probability the pointer will land on blue is 2 out of 8.
The probabilities that the pointer will land on green or red are both 25%.
Yes, the probabilities of the pointer landing on each of the colored sections of the spinner are the same. Since each outcome is equally likely, the spinner is fair.
