Answer:
possible outcomes
Step-by-step explanation:
For any experiment, the sample space of this experiment is the set of all the possible results of the experiment.
In this case we have two spinners. The first has 5 colors, by spinning the spinner you can get up to 5 different results. Therefore the sample space is
For the second spinner there are 3 possible results. By spinning the spinner you can get the numbers 1, 2 or 3. Then .
Then, if the two spinners are rotated, the sample space would be:
possible outcomes.
The tree diagram shown in the attached image shows the 15 possible results
{R, 1} {R, 2} {R, 3} {O, 1} {O, 2} {O, 3} {Y, 1} {Y, 2} {Y, 3} {P, 1} {P, 2} {P, 3} {G, 1}
{G, 2} {G, 3}
