Find the theoretical probability of spinning a D on the spinner. Look at the figure.

To calculate the theoretical probability of spinning a "D" on a spinner, we would generally follow these steps:

1. ### Break Down the Problem

1. Determine the total number of sections on the spinner.
2. Identify the number of sections that contain "D".

2. ### Relevant Concepts

The theoretical probability $P$ is calculated using the formula:

$P(D) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$

3. ### Analysis and Detail

1. Let's assume the total number of sections on the spinner is denoted as $n$.
2. Let $m$ be the number of sections that have "D".

4. ### Verify and Summarize

1. Calculate $P(D)$ using the values of $m$ and $n$.
2. Ensure the values are accurate and make sense in the context.

Final Answer

If, for example, there are 4 sections in total on the spinner and 1 section has "D", then:

$P(D) = \frac{1}{4} = 0.25 \quad \text{or} \quad 25\%$

Please provide the figure or additional details for accurate calculations.
