To find the probability \( P(purple) \), we need to identify the number of favorable outcomes (landing on a purple section) and the total number of possible outcomes (all sections on the spinner).
Given that the spinner has 4 equal-sized sections and you typically would have 1 of these sections be purple, we can conclude:
- Favorable outcomes (Landing on purple): 1 (assuming there is 1 purple section)
- Total outcomes (Total sections): 4
Now we can write the probability:
\[ P(purple) = \frac{\text{favorable outcomes}}{\text{total outcomes}} = \frac{1}{4} \]
Thus, the completed statement will be:
\[ P(purple) = \frac{1}{4} \]
Therefore, the answer is:
\[ \text{equals} , \frac{1}{4} \]
