Out of the 10 sections, 5 are even and 5 are odd. Therefore, the probability of getting an even number is 5/10 or 1/2.
To find the probability of not getting an even number, we can subtract the probability of getting an even number from 1.
P(not even) = 1 - P(even)
P(not even) = 1 - 1/2
P(not even) = 1/2
So the answer is option B: one-half.
