Question

you spin the spinner shown below once. each sector shown has an equal area. what is p(not shaded sector)? if necessary, round your answer to 2 decimal places.

Explanation:

Step1: Count total and non - shaded sectors

Total sectors = 10. Non - shaded sectors = 4.

Step2: Use probability formula

Probability \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). So \(P(\text{not shaded})=\frac{4}{10}\).

Step3: Simplify the fraction

\(\frac{4}{10}=0.4\)

Answer:

\(0.4\)
