To determine the number of possible outcomes when a spinner that has three equal parts labeled 1, 2, and 3 is spun three times, we can use the formula for the number of outcomes of repeated independent events.
Each spin has 3 possible outcomes (1, 2, or 3). Since the spins are independent, you would multiply the number of outcomes for each spin together:
\[ \text{Total Outcomes} = \text{Outcomes per spin} ^ \text{Number of spins} \]
In this case:
\[ \text{Total Outcomes} = 3^3 = 27 \]
Thus, the number of possible outcomes when the spinner is spun three times is 27.
