Final answer:
Spinning a four-section spinner twice results in 16 possible outcomes since each spin has 4 possible results.
Step-by-step explanation:
When spinning a spinner with four equal sections (red, blue, green, and yellow) two times, we can determine the number of possible outcomes by multiplying the number of outcomes for each spin.
In this case, each spin has 4 possible outcomes.
So, the total number of possible outcomes for two spins is 4 x 4 = 16.
