I believe the answer you looking for is Probability.
This means that if someone spinned that wheel, they have a probability of getting the color they need.
For instance, Let's say this wheel had the colors red, orange, yellow, green, blue, indigo, purple, and pink. If I wanted the color red on the spinner, I have a 1/8 chance to spin the color red. I have a 7/8 chance of NOT spinning red. However, let's say the wheel had 4 colors that were pink and 4 colors that were blue. If I wanted to spin the color pink, I would have a 4/8 chance OF spinning it and a 4/8 chance of NOT spinning it. 4/8 is also equivilant to 1/2.
I hope this helps you understand!! Please mark brainliest!! Thanks!!
