Question

example 2. the spinner shown is divided into congruent sections. if the spinner is spun one time, what is the probability of the arrow not landing on a section labeled with an odd number? a \\(\frac{5}{8}\\) b \\(\frac{1}{8}\\) c \\(\frac{3}{8}\\) d \\(\frac{7}{8}\\)

Explanation:

Step1: Count total sections

Total sections = 8

Step2: Identify odd-numbered sections

Odd numbers: 1, 3, 5, 9, 11 → Count = 5

Step3: Calculate even section count

Even sections = Total - Odd = $8 - 5 = 3$

Step4: Compute target probability

Probability = $\frac{\text{Even sections}}{\text{Total sections}} = \frac{3}{8}$

Answer:

C. $\frac{3}{8}$
