Final answer:
The theoretical probability of spinning an odd number on the spinner is 1/2.
Step-by-step explanation:
To find the theoretical probability of spinning an odd number on the spinner, we need to determine the number of favorable outcomes (odd numbers) and divide it by the total number of possible outcomes.
In this case, the spinner has 6 equal sections labeled 1, 2, 3, 4, 5, and 6.
Of these sections, the odd numbers are 1, 3, and 5, which means there are 3 favorable outcomes.
Since there are a total of 6 possible outcomes, the theoretical probability of spinning an odd number is 3/6 or 1/2.
