A spinner is divided into 11 equal sections numbered from 0 to 10. You spin the spinner once. What is P(even)?

A. start fraction 3 over 5 end fraction
B. one-half
C. Start Fraction 5 over 11 End Fraction
D. Start Fraction 6 over 11 End Fraction

There are 5 even numbers on the spinner: 0, 2, 4, 6, and 8. Out of the 11 possible outcomes, the probability of getting an even number on the spinner is 5/11. Therefore, the answer is C. Start Fraction 5 over 11 End Fraction.
