Question

you spin the spinner once. what is p(not 9)? write your answer as a percentage.

Explanation:

Step1: Determine total sections

The spinner has 4 equal sections.

Step2: Find sections not 9

Sections with numbers other than 9: 6, 7, 8. So there are 3 such sections.

Step3: Calculate probability

Probability \( P(\text{not } 9) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{3}{4} \)

Step4: Convert to percentage

\( \frac{3}{4} \times 100\% = 75\% \)

Answer:

75
