There are 27 different possible outcomes if you spin 3 spinners labeled Red, Blue, Yellow.

How to think about it

Each spinner has 3 possible results: Red , Blue , or Yellow.

Since the 3 spinners are independent, you multiply the number of options:

Total outcomes=3×3×3=33=27\text{Total outcomes}=3\times 3\times 3=3^3=27Total outcomes=3×3×3=33=27

An example outcome looks like a 3-color sequence, such as (Red, Blue, Yellow) or (Yellow, Yellow, Red).

TL;DR: With 3 colors on each of 3 independent spinners, you get 33=273^3=2733=27 possible outcomes.
