There are 5 even numbers (2, 4, 6, 8, 9) and 4 odd numbers (1, 3, 5, 7).
P(not odd) = P(even or 9) = P(even) + P(9)
P(even) = 5/9 (since there are 5 even numbers out of 9 total)
P(9) = 1/9 (since there is only one section with 9)
P(not odd) = 5/9 + 1/9 = 6/9 = 2/3
Therefore, the probability of spinning a number that is not odd is 2/3 or about 0.67.
A spinner is divided into 9 equal sections numbered from 1 to 9. You spin the spinner once. What is P(not odd)?
